DESCRIPTION
FEATURES
• Switching at low ON resistance
• Wide range of supply voltages: V
• Prevention of reverse current from the load at switch-off time
• ON time controllable with external pin
• Break-before-make operation
PACKAGE
When data is written to or read from flash memory, it requires that the voltage at its power supply (V
(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
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
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
operation).

... PP When conditions, EN1 = “H” and EN0 = “L” are established in an attempt to write data to flash memory, the switch- on circuit (charge pump) on the SW1 side is activated. The charge pump applies optimum voltage to the SW1 gate to turn the switch on, causing the SWOUT pin to supply 12-V power from the SWIN1 pin to the V the SW2 gate voltage to the GND to turn the switch off ...
