Description
The 10410 is a high-side driver for automotive applications. It can drive small lamps, relays, coils etc. The output current can be up to 250mA per driver (current limit at minimum 250mA). The IC will only react to commands on the bus if the CEN (chip enable) signal is high. The CEN signal has nothing to do with the power down mode, the IC will react to the micro controller commands if CEN is high.

In order to switch a particular output, it is necessary to apply its address on the 3 bit bus and the data on the input DATAI. A high level on STROBE will latch the data and switch the output. When the IC is in active mode and CEN is high, the logic level of the addressed output will be available on the pin DATAO. When all 8 outputs are inactive (latched value is low) the circuit automatically switches to power down mode. Diagnostic mode: when the DATAI is low and the STROBE is high, a 50K pull up to VCC is switched on, on the corresponding output channel (addressed by ADR2, ADR1, ADR0) to see whether there is a load connected. The logic level of the output can be observed on the pin DATAO. In this way, it is possible to scan all the outputs for an open circuit. When the IC is in active mode, then there is an over-temperature sensor that monitors the temperature of the IC. If the die temperature goes above 165C, all outputs are switched off and the output OTB will go low. As soon as the temperature decreases below 125C all outputs are switched back to their previous state. The outputs are short-circuit proof against GND and VCC. When an output is shorted to GND, the current is limited and, after a delay of typically 20ms, the output is switched off and the output OTB goes low. A delay is used to guarantee that the output does not detect a short circuit when a normal lamp is driven. The latched value of the ouput is set to 0. A rising edge on CEN will set OTB back to 1. When an output is shorted to a supply larger than VCC+100mV, the output driver bulk is immediately disconnect from VCC, and after a delay of typically 20ms, the output is switched off and the output OTB goes low. The latched value of the ouput is set to 0. A rising edge on CEN will set OTB back to 1 There is an over-voltage shut off that switches all the outputs off when the VCC voltage is above 18V for at least 1ms. When an over-voltage occurs, CEN being low, DATAO pin will go low. The outputs will come on again as soon as the voltage decreases below 18V. The status of all 8 outputs stays latched. Every output stage is protected with a free wheel diode both to ground and to VCC.

Reliability Information
Melexis devices are classified and qualified regarding suitability for infrared, vapor phase and wave soldering with usual (63/37 SnPb-) solder (melting point at 183degC). The following test methods are applied: IPC/JEDEC J-STD-020A (issue April 1999) Moisture/Reflow Sensitivity Classification For Nonhermetic Solid State Surface Mount Devices CECC00802 (issue 1994) Standard Method For The Specification of Surface Mounting Components (SMDs) of Assessed Quality MIL 883 Method 2003 / JEDEC-STD-22 Test Method B102 Solderability

For all soldering technologies deviating from above mentioned standard conditions (regarding peak temperature, temperature gradient, temperature profile etc) additional classification and qualification tests have to be agreed upon with Melexis. The application of Wave Soldering for SMD's is allowed only after consulting Melexis regarding assurance of adhesive strength between device and board.
