Power Management Switching IC
(with flash memory power switching function)
MB3807A

DESCRIPTION
When data is written to or read from flash memory, it requires that the voltage at its power supply (V
PP
) 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 V
PP
voltage of flash memory.
When the switch is turned on, optimum voltage is applied to the gate of the internal charge pump N-ch MOS
switch, providing a constant amount of ON resistance. The ON resistance is also kept to be low to reduce voltage
drop at the V
PP
pin that is caused by large current flowing when data is written.
In addition, the OFF time is much shorter than the ON time to prevent short-circuiting between the reading and
writing power supplies when the device switches the V
PP
voltage for reading or writing data (break-before-make
operation).

FEATURES
Switching at low ON resistance
For writing data: SWIN1 = 12 V, Ron = 0.3
For reading data:SWIN2 = 5 V, Ron = 6.0
SWIN2 = 3.3 V, Ron = 8.5
Wide range of supply voltages: V
CC
= 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

PACKAGE
16 pin Plastic SOP
(FPT-16P-M04)
