Open load detection in off-state
Off-state open load detection requires an external pull-up resistor (R
OUTPUT pin and a positive supply voltage (V
microprocessor.
The external resistor has to be selected according to the following requirements:
1) no false open load indication when load is connected: in this case we have to avoid V
to be higher than V
V
2) no misdetection when load is disconnected: in this case the V
