PIN ASSIGNMENTS AND FUNCTIONS
Pin #
Pin Name
Pin Description
1
+3.3 V
aux
Auxiliary input. Typical voltage 3.3 V.
2
+5.0 V
in
This is the input supply for the IC. Typical voltage 5.0 V. (Notes 1 and 2)
3
Gnd
Logic and power ground.
4
+3.3 V
out
3.3 V output provided to the application circuit (output current is sourced to this pin from the
5.0 V input.)
5
Drive out
This output drives a Pchannel MOSFET with up to 2000 pF of “effective” gate capacitance.
Recommended devices are the MMFT5P03HD and MTSF1P02HD. Drive out has active internal
pullup and pulldown circuitry to guarantee fast transitions.
