Description
CMOS compatible input. Pins 1, 2, 3, 7, 8 no connection on 751G.
Output to load and battery, protected by a 60 V clamp against inductive
load transients.
Ground connection.
Fault output pulled low when the IC is operating in a fault state. The open drain
output requires a pull–up resistor for normal operation.

Definition of Currents and Voltages. Positive current flow is defined as conventional current flow into the
device. Negative current flow is defined as current flow out of the device. All voltages are referenced to ground.
Both currents and voltages are specified as absolute (i.e., –10 V is greater than –1.0 V).
