General Description
The FPF2200-FPF2202 are low R DS(ON) P-Channel MOSFET
load switches with high precision current limit value. The input
voltage range operates from 1.8V to 5.5V to fulfill today's Ultra
Portable Device's supply requirement. Switch control is by a
logic input (ON) capable of interfacing directly with low voltage
control signal. On-chip pull-down is available for output quick

Ordering Information
Pin 1
For the FPF2201, if the constant current condition still persists
after 30ms, these parts will shut off the switch and pull the fault
signal pin (FLAGB) low. The FPF2200 has an auto-restart
feature which will turn the switch on again after 450ms if the ON
pin is still active. The FPF2201 do not have this auto-restart
feature so the switch will remain off until the ON pin is cycled.
For the FPF2202, a current limit condition will immediately pull
the fault signal pin low and the part will remain in the constant-
current mode until the switch current falls below the current
limit. For the FPF2200 through FPF2202, the minimum current
limit is 500mA with 5% accuracy.
