Product Specifications

The R5542 is a Nch. load switch IC with a voltage detector. The R5542 is an ideal load switch IC for supplying the power from the battery to the load circuit. A built-in Nch. driver transistor with typically 9 mΩ ON resistance allows the R5542 to provide a low dropout voltage and prevents the reverse current during shutdown mode. Internally, the R5542 consists of an internal voltage step-up circuit, a soft-start circuit, a chip enable circuit and a UVLO circuit.

The R5542 is offered in an ultra-small WLCSP-12-P3 package which can achieve the smallest possible footprint solution on boards where area is limited.
