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 kΩ) Output Stage: – Short-circuit Protected – Load-dump Protected at 1 k Ω – 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. Figure 1. Block Diagram
