FUNCTION DESCRIPTION
With a capacitor connected from this pin to GND sets the delay time for start-up sequence and sets the fault
timeout time
Gate driver output for the external N channel switch; the pulse voltage follows the input voltage
Power GND
With a resistor connected from this pin to GND sets the current limit of the external N channel FET
Sense the drain voltage of the external N channel FET and connected to the internal current limit comparator
Active low control output for optional delay control for external V BOOST P channel FET; when fault is detected,
this pin goes to high
Low noise signal ground
Boost regulator voltage feedback input pin; regulates to 1.2V nominal
V BOOST integrator output, connect 2.2nF to analog GND for PI mode or connect to V REF for P mode operation
Bandgap voltage bypass terminal; bypass with a 0.1μF to analog GND; can be used as charge pump reference
Negative LDO voltage feedback input pin; regulates to 0.2V nominal
Negative LDO base drive; open drain of an internal P channel MOSFET
Logic LDO voltage feedback input pin; regulates to 1.2V nominal
Logic LDO base drive; open drain of an internal N channel MOSFET
Positive LDO voltage feedback input pin; regulates to 1.2V nominal
Positive LDO base drive; open drain of an internal N channel MOSFET
Enable pin for the chip; high enable; low disabled
Positive supply for all internal circuitry except DRVB
Positive supply for external N channel FET gate drive (DRVB)
Output gate drive of the external fault protection P channel FET; when chip is disabled or when a fault has
been detected, this pin is high
