MB3802 - Power Management Switch

Datasheet Summary

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.

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 s.

FUJITSU SEMICONDUCTOR DATA SHEET DS04-27601-2E ASSP For Power Supply Applications 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.
