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

1. See 5.0 V Detect Thresholds Diagram.
2. Recommended source impedance for 5.0 V supply: ≤ 0.12 W. This will ensure that Io x Rsource < Vhyst, thus avoiding driveout toggling during
5.0 V detect threshold transitions.
3. Vin should not be allowed to go negative relative to ground.
4. Mounted on recommended minimum PCB pad on FR4, 2–oz. copper circuit board.
5. AC specs are guaranteed by characterization, but not production tested after characterization.
6. See Figure 3. Application Block Diagram.
7. See Timing Diagram.
