Fujitsu MB3790

The MB3790 is designed to control power supplies to SRAM, logic IC, or other circuit devices and protects them against momentary power failures by using backup batteries. Ideally designed as a single-chip IC for power supply control, the MB3790 consumes only a minimal current and comes in a thin-type package.

APPLICATIONS

Bi-CMOS Battery Backup IC MB3790 s

DESCRIPTION

In addition to its function to supply the power to these devices, it has a function to switch the source of power to the primary or secondary backup battery when the power supply voltage drops below a predetermined level. Also, it outputs a reset signal when the power supply turns on or off or when a fault occurs in the power supply. Therefore, it is best suited for power supply control in memory cards and similar DataSheet4U.com other devices. DataShee s
