The RT2528A is a cost effective, low voltage, P-MOSFET power switch IC with an adjustable current limit feature. Low on-resistance (74mΩ typ.) and low supply current (120μA typ.) are designed in this IC.

The RT2528A offers 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 RT2528A is an ideal solution for power supply applications since it is functional for various current limit requirements. The RT2528A is available in the thermal enhanced SOP-8 (Exposed Pad) package.
