General Description
The FPF1005 & FPF1006 are low RDS P-Channel MOSFET
load switches with CMOS controlled turn-on targeting small
package load switch applications. The input voltage range
operates from 1.2V to 5.5V. Switch control is by a logic
input (ON) capable of interfacing directly with low voltage
control signals. In FPF1006, 120Ω on-chip load resistor is
added for output quick discharge when switch is turned off.
Both FPF1005 & FPF1006 are available in a small 2X2
MicroFET-6 pin plastic package.

Description of Operation
The FPF1005 & FPF1006 are low R
switches with controlled turn-on. The core of each device is a
55mΩ P-Channel MOSFET and a controller capable of
functioning over a wide input operating range of 1.2-5.5V. The
ON pin, an active HI TTL compatible input, controls the state of
the switch. The FPF1006 contains a 120Ω on-chip load resistor
for quick output discharge when the switch is turned off.
However, V
pin of FPF1006 should not be connected
OUT
directly to the battery source due to the discharge mechanism of
the load switch.
