Outputs in PNP Mode: Electrical Details
When the outputs are configured for PNP mode (source driver) the user is required to provide the
output supply voltage (USR_PWR). A simplified schematic and important output specifications

User provides the output power supply voltage ( 7 volts to 35 volts ).
Maximum source driver output current is 350 mA.
Source driver with over-current protection (all outputs will shut down simultaneously). The over-
current fault circuit will protect the device from short-circuits to ground with supply voltages of
up to 35V.
