Parameter
Parameter
This is the input supply for the IC. Typical voltage 5 V. (1) (2)
Reserved
Auxiliary input. Typical voltage 3.3 V.
Logic and Power Gnd.
Load–sense voltage input to internal regulator.
3.3V output provided to the application circuit (output current is sourced to this pin from the 5V input.)
This output drives a P–channel MOSFET with up to 2000pF of “effective” gate capacitance.
Recommended device is MGSF1P02ELT MOSFET. Drive out has active internal pull–up and
pull–down circuitry to guarantee fast transitions.
