Ω, 2.5A Power Switch with Adjustable Current Limit

General Description

The RT2528 is a cost effective, low voltage, P-MOSFET

power switch IC with an adjustable current limit feature.

Low on-resistance (74m

Ω typ.) and low supply current

(120

μA typ.) are designed in this IC.

The RT2528 can offer an adjustable current limit threshold

between 0.5A and 2.5A (typ.) via an external resistor. The

±10% current limit accuracy can be realized for all current

limit settings.

The RT2528 is an ideal solution for power supply

applications since it is functional for various current limit

requirements. The RT2528 is available in the thermal

enhanced SOP-8 (Exposed Pad) package.
