Overview
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 su...
