NOTES: (1.) See 5V Detect Thresholds Diagram.
W (2.) Recommended source impedance for 5V supply: ≤ 0.25 . This will ensure that Io x Rsource < Vhyst, thus avoiding
driveout toggling during 5V detect threshold transitions.

PIN ASSIGNMENTS AND FUNCTIONS
PIN #
PIN NAME
PIN DESCRIPTION
1
+5 Vin
This is the input supply for the IC. Typical voltage 5 V. ^{(1) (2)}
2,5
N/C
Reserved
3
+3.3 Vin
Auxiliary input. Typical voltage 3.3 V.
4
Gnd
Logic and Power Gnd.
6
Sense in
Load–sense voltage input to internal regulator.
7
+3.3 Vout
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.
8
Drive out
Recommended device is MGSF1P02ELT MOSFET. Drive out has active internal pull–up and
pull–down circuitry to guarantee fast transitions.
