General Description
The FPF2223-FPF2225 are low RDS(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
discharge when switch is turned off.
For the FPF2224, 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 FPF2223 has an auto-restart
feature, which will turn the switch on again after 450mS if the
ON pin is still active. The FPF2224 do not have this auto-restart
feature so the switch will remain off until the ON pin is cycled.
For the FPF2225, 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 FPF2223 through FPF2225, the current limit is set
by an external resistor and the minimum current limit is 250mA.
