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 voltage of flash memory. When the switch is turned on, opti.

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 time controllable with external pin
• Break-before-make operation s PACKAGE 16 pin Plastic SOP (FPT-16P-M04) MB3807A s PIN ASSIGNMENT (TOP VIEW) EN1A EN0A SWIN2A SWIN1A SWIN1B SWIN2B EN0B GND 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VCC DLYA SWOUTA SWOUTA SWOUTB SWOUTB DLYB EN1B (FPT-16P-M04) s LOGICAL OPERATION TABLE EN1 0 .
