RT2528
120mΩ, 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 (74mΩ typ.) and low supply current
(120μA 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.
