Ground connection for control chip
Input: activates power switch. Has an internal pull down resistor.
Sense Output: With diagnosis enabled, provides a sense current proportional to the
load current during normal operation. During open load in ON provides no current.
Provides a defined fault current in case of overload, over temperature or short circuit
during ON or open load or short to battery during OFF (see
Page
Diagnosis ENable: with high level enables diagnosis reporting and open load / short to
battery detection in OFF. Resets a protective, latched switch-off by falling edge
acknowledgement. Has an internal pull down resistor.
Not connected
Output: output to the load; pins 8 to 11 must be externally shorted together
Supply Voltage: positive power supply for logic and output
