ELECTRICAL CHARACTERISTICS (continued)
LOGIC INPUT (Per each channel)
Note 1 : The input voltage is internally clamped at 32V minimum , it is possible to connect the input pins to an higher voltage via an external
resistor calculate to not exceed 10mA.
PROTECTION AND DIAGNOSTICS
(*) Status determination > 100µs after the switching edge.
Note: If INPUT pin is floating the corrisponding channel will automatically switch off. If GND pin is disconnected, the channel will switch off
provided V
