This application circuit does not guarantee its operation.
When using the circuit with changes to the external circuit constants,
make sure to leave an adequate margin for external components including
AC/DC characteristics as well as dispersion of the IC.
Datasheet
Functional Description
1. Switch Operation
IN and OUT are connected to the MOSFET’s drain and source. By setting the EN input to high, the internal charge
pump operates and turns on the MOSFET. When the MOSFET is turned on, the switch becomes bi-directional.
Consequently, when VIN < VOUT, the current is flowing from OUT to IN.
2. Output Discharge Circuit
The output discharge circuit operates when the switch is turned off. During its operation, a 70Ω (Typ) resistor is
connected between OUT and GND. Unwanted electrical charge is discharged quickly into this resistor.
