Description

The FPF1003A and FPF1004 are low RDS P-channel MOSFET load switches with controlled turn-on. The input voltage range operates from 1.2 V to 5.5 V to fulfill todays ultra-portable device supply requirements. Switch control is accomplished with a logic input (ON) capable of interfacing directly with low-voltage control signal. In FPF1004, a 120 Ω on-chip load resistor is added for output quick discharge when the switch is turned off.

Both FPF1003A and FPF1004 are available in a spacesaving 1.0x1.5 mm2 wafer-level chip-scale package.
