DESCRIPTION
The BQ20Z90 SBS-compliant gas gauge IC, incorporating patented Impedance TrackTM technology, is designed for battery-pack or in-system installation. The BQ20Z90 measures and maintains an accurate record of available charge in Li-ion or Li-polymer batteries using its integrated high-performance analog peripherals. The BQ20Z90 monitors capacity change, battery impedance, open-circuit voltage, and other critical parameters of the battery pack, and reports the information to the system host controller over a serial-communication bus. It is designed to work with the bq29330 analog front-end (AFE) protection IC to maximize functionality and safety, and minimize component count and cost in smart battery circuits. The Impedance Track technology continuously analyzes the battery impedance, resulting in superior gas-gauging accuracy. This enables remaining capacity to be calculated with discharge rate, temperature, and cell aging all accounted for during each stage of every cycle. AVAILABLE OPTIONS

FEATURE SET Primary (1st Level) Safety Features
The BQ20Z90 supports a wide range of battery and system protection features that can easily be configured. The primary safety features include: * * * * * * * * Battery cell over/under voltage protection Battery pack over/under voltage protection 2 independent charge overcurrent protection 3 independent discharge overcurrent protection Short circuit protection Over temperature protection AFE Watchdog Host Watchdog
Secondary (2nd Level) Safety Features
The secondary safety features of the BQ20Z90 can be used to indicate more serious faults via the SAFE (pin 10) pin. This pin can be used to blow an in-line fuse to permanently disable the battery pack from charging or discharging. The secondary safety features include: * * * * * * * * * * * * Safety over voltage Battery cell imbalance 2nd level protection IC input Safety over current Safety over temperature Open thermistor Charge FET and Zero-Volt Charge FET fault Discharge FET fault Fuse blow failure detection AFE Communication error AFE Verification error Internal flash data error
Charge Control Features
The BQ20Z90 charge control features include: * * Report the appropriate charging current needed for constant current charging and the appropriate charging voltage needed for constant voltage charging to a smart charger using SMBus broadcasts. Determine the chemical state of charge of each battery cell using Impedance TrackTM. Using cell balancing algorithm, gradually decrease the differences in the cells' state of charge in a fully charged state. This prevents high cells from overcharging, causing excessive degradation and also increases the usable pack energy by preventing early charge termination. Support Pre-charging/Zero-volt charging Support Fast charging Support Pulse charging Support Charge Inhibit and Charge Suspend modes Report charging faults and also indicate charging status via charge and discharge alarms.
* * * * *
Gas Gauging
The BQ20Z90 uses the Impedance TrackTM Technology to measure and calculate the available charge in battery cells. The achievable accuracy is better than 1% error over the lifetime of the battery and there is no full charge-discharge learning cycle required.

See Theory and Implementation of Impedance Track Battery Fuel-Gauging Algorithm application note (SLUA364) for further details.
LED Display
The BQ20Z90 can drive a 3-, 4-, or 5- segment LED display for remaining capacity indication. The LED drive current can be adjusted to 3mA, 4mA and 5mA digitally.
LifeTime Data Logging Features
The BQ20Z90 offers a lifetime data logging array, where all important measurements are stored for warranty and analysis purposes. The data monitored include: * * * * * * * * * * * * * Lifetime Lifetime Lifetime Lifetime Lifetime Lifetime Lifetime Lifetime Lifetime Lifetime Lifetime Lifetime Lifetime maximum temperature minimum temperature maximum battery cell voltage minimum battery cell voltage maximum battery pack voltage minimum battery pack voltage maximum charge current maximum discharge current maximum charge power maximum discharge power maximum average discharge current maximum average discharge power average temperature
Authentication The BQ20Z90 supports authentication by the host using SHA-1. Power Modes The BQ20Z90 supports 3 different power modes to reduce power consumption: * * * In Normal Mode, the BQ20Z90 performs measurements, calculations, protection decisions, and data updates in 1 second intervals. Between these intervals, the BQ20Z90 is in a reduced power stage. In Sleep Mode, the BQ20Z90 performs measurements, calculations, protection decisions, and data updates in adjustable time intervals. Between these intervals, the BQ20Z90 is in a reduced power stage. In Shutdown Mode the BQ20Z90 is completety disabled.
CONFIGURATION
Oscillator Function The BQ20Z90 fully integrates the system and processor oscillators and, therefore, requires no pins or components for this feature. System Present Operation The BQ20Z90 periodically verifies the PRES pin and detects that the battery is present in the system via a low state on a PRES input. When this occurs, BQ20Z90 enters normal operating mode. When the pack is removed from the system and the PRES input is high, the BQ20Z90 enters the battery-removed state, disabling the charge, discharge and ZVCHG FETs. The PRES input is ignored and can be left floating when non-removal mode is set in the data flash.

FEATURE SET (continued) BATTERY PARAMETER MEASUREMENTS
The BQ20Z90 uses an integrating delta-sigma analog-to-digital converter (ADC) for current measurement, and a second delta-sigma ADC for individual cell and battery voltage, and temperature measurement. Charge and Discharge Counting The integrating delta-sigma ADC measures the charge/discharge flow of the battery by measuring the voltage drop across a small-value sense resistor between the SRP and SRN pins. The integrating ADC measures bipolar signals from -0.25 V to 0.25 V. The BQ20Z90 detects charge activity when VSR = V(SRP)-V(SRN)is positive and discharge activity when VSR = V(SRP)-V(SRN) is negative. The BQ20Z90 continuously integrates the signal over time, using an internal counter. The fundamental rate of the counter is 0.65 nVh. Voltage The BQ20Z90 updates the individual series cell voltages through the bq29330 at one second intervals. The BQ20Z90 configures the bq29330 to connect the selected cell, cell offset, or bq29330 VREF to the CELL pin of the bq29330, which is required to be connected to VIN of the BQ20Z90. The internal ADC of the BQ20Z90 measures the voltage, scales it, and calibrates itself appropriately. This data is also used to calculate the impedance of the cell for the Impedance TrackTM gas-gauging. Current The BQ20Z90 uses the SRP and SRN inputs to measure and calculate the battery charge and discharge current using a 5 m to 20 m typ. sense resistor. Wake Function The BQ20Z90 can exit sleep mode, if enabled, by the presence of a programmable level of current signal across SRP and SRN. Auto Calibration The BQ20Z90 provides an auto-calibration feature to cancel the voltage offset error across SRP and SRN for maximum charge measurement accuracy. The BQ20Z90 performs auto-calibration when the SMBus lines stay low continuously for a minimum of a programmable amount of time.
Temperature
The BQ20Z90 TS1 and TS2 inputs, in conjunction with two identical NTC thermistors (default are Semitec 103AT), measure the battery environmental temperature. The BQ20Z90 can also be configured to use its internal temperature sensor.
COMMUNICATIONS
The BQ20Z90 uses SMBus v1.1 with Master Mode and package error checking (PEC) options per the SBS specification. SMBus On and Off State The BQ20Z90 detects an SMBus off state when SMBC and SMBD are logic-low for 2 seconds. Clearing this state requires either SMBC or SMBD to transition high. Within 1 ms, the communication bus is available. Table 1. SBS COMMANDS
