Description

The FPF2165R is a load switch which provides full

protection to systems and loads which may encounter

large current conditions. The device contains a 0.12

Ω

current-limited Pchannel MOSFET which can operate

over an input voltage range of 1.8-5.5 V. Internally,

current is prevented from flowing when the MOSFET is

off and the output voltage is higher than the input

voltage. Switch control is by a logic input (ON) capable

of interfacing directly with low-voltage control signals.

The FPF2165R contains thermal shutdown protection,

which shuts off the switch to prevent damage to the part

when a continuous over-current condition causes

excessive heating.

When the switch current reaches the current limit, the

part operates in a Constant-Current (CC) mode to

prohibit excessive currents from causing damage. The

FPF2165R does not turn off after a current limit fault; it

remains in the constant current mode indefinitely. The

minimum current limit is 150 mA.

The FPF2165R is available in a space-saving 6-pin

2 mm x 2 mm Molded Leadless Package (MLP).
