MB3807A Datasheet (Fujitsu Media Devices) - Power Management Switching

MB3807A, Power Management Switching

When data is written to or read from flash memory, it requires that the voltage at its power supply (VPP) be switched (to 12 V for writing and to 3.3 or 5.0 V for reading).

The MB3807A is a power management switching IC, designed to be compatible with the PCMCIA digital controller, to switch the VPP

MB3807A Features

* Switching at low ON resistance For writing data: SWIN1 = 12 V, Ron = 0.3 Ω For reading data: SWIN2 = 5 V, Ron = 6.0 Ω SWIN2 = 3.3 V, Ron = 8.5 Ω

* Wide range of supply voltages: VCC = 2.7 to 5.5 V

* Prevention of reverse current from the load at switch-off time

* ON
