Power Management Switch

MB3802

s DESCRIPTION

The MB3802 is a power management switch incorporating two switch circuits with extremely low ON resistance.

NO diode is required because the switch block is configured with an N-ch MOS to prevent reverse current at

switch OFF.

The MB3802 starts at a very low voltage (typical VIN > 2.2V) and a stable ON resistance is obtained irrespective

of the switching voltage because the internal DC/DC converter applies the optimum voltage for the N-ch MOS

gate at switch ON.

Moreover, the load-side capacitor is discharged at switch OFF, and the power supply for various power supply

systems is switched efficiently.

s FEATURES

• Extremely low ON resistance:

RON = 0.12 Ω (typical)

RON = 0.06 Ω (typical at parallel connection)

• Reverse current protection at load side at switch OFF

• Operation start at low input voltage: VIN > 2.2 V (typical)

• Low power consumption

At switch OFF: IIN (input voltage) = 0 µA, VIN = 0 V

At switch ON: IIN = 230 µA, VIN = 5 V

• Load discharge function

• External control of ON/OFF time

• Break-before-make operation
