Fun ction
Supply Voltage
Channel 2: Push-Pull power output with intrinsic body diode
NC: Not Connected
Ground: signal - and power - ground, heat sink
Input 2: Schmitt Trigger input with hysteresis (non-inverting signal control)
Enable: LOW or not connected on this input switches the device into standby mode and the
outputs into tristate
Diagnostic: Open Drain Output that switches LOW if overvoltage or overtemperature is
detected
Input 1: Schmitt Trigger input with hysteresis (non-inverting signal control)
