Features * * * * * * Input Comparator with Schmitt-trigger Characteristic Input Clamping Current Capability of 10 mA Integrated Protection Cells (EMC, ESD, RF) Dedicated to All Input Stages Shutdown by Junction-temperature Monitor Reset with Hysteresis at Low Voltage ESD Protection Acording to Human Body Model: 2000 V (C = 100 pF, R = 1.5 k) * Output Stage: - Short-circuit Protected - Load-dump Protected at 1 k - Jump Start Possible Description The singel-channel driver IC includes one non-inverted and current-limited output stage with an open collector. Thermal shutdown protects the output against critical junction temperatures. The output can sink a current of 20 mA. The digital input has Schmitt-trigger function with pull-up resistors to 5 V.

An external buffer capacitor of C = 100 nF is recommended. An integrated 14 V Zener diode between VS and ground protects the supply pin. The input stage is provided with an integrated 250 kW pull-up resistor and can be directly connected to a microcontroller. The output stage is an open collector, capable of sinking 20 mA. Recommended external components: * * Pull-up resistor, R = 1 kW Capacitor to GND, C = 470 pF, see Figure 3 Functional Description General ON state: Low level at the input stage activates the output stage. OFF state: The internal pull-up resistor provides high level to the input comparator and deactivates the output stage. A 7 V Zener diode between input pin and GND is capable of 10 mA clamping current. Current Limitation of the Output Stages and Overtemperature Shutdown Transients and Load Dump A temperature-dependent current limitation in the range of 25 to 100 mA protects the stage in case of a short circuit. Additionally, the chip temperature is monitored. For TChip > 148C, the output is disabled and automatically enabled with a hysteresis of TChip > 5C. An integrated 28 V Zener diode protects the output stage against transients and loaddump (Schaffner pulses). With the help of an external 1 kW resistor, the output transistor is capable of handling the corresponding current which flows during each of these conditions. Apart from that, the output is short-circuit and overload protected. When the supply voltage is switched on, a power-on reset pulse is generated internally which disables the output stage until a defined supply-voltage level is reached. The lowvoltage detection is provided with a hysteresis of Vhyst = 0.5 V typically. Figure 3.
