Advanced Power Electronics Corp. announces miniature ultra-low RDS(ON) dual load switch

Reduce system power in power rail management applications

May 2013, San Jose, CA…Advanced Power Electronics Corp. (USA), a leading Taiwanese manufacturer of MOS power semiconductors for DC-DC power conversion applications, has announced a miniature, ultra-low on-resistance 6A dual load switch. Comprising two N-channel MOSFETs with associated control circuitry, the APE8990-3 has an RDS(ON) of 20mO and controlled turn on functionality.

 The MOSFETs operate over an input voltage range of 0.8 to 5.5V and each support a maximum current of 6A. Each load switch is controlled by an ON/OFF input (ON), which is capable of interfacing directly with the low voltage control signals. Additional features include an on-chip 150? load resistor for quick output discharge when the switch is turned off. In order to avoid inrush current, the rise time is adjustable using an external ceramic capacitor on the CTx pin.

Comments Ralph Waggitt, President/CEO, Advanced Power Electronics Corp. (USA): “This is a very useful device, suitable for many applications as a load switch for power rail management. As an example, it can be used to turn off power to idle sub-systems, reducing system power consumption and thereby improving battery life in portable applications.”

The APE8990-3 is available in an ultra small, space-saving 3x2mm 14-pin DFN package with a thermal pad. Download the datasheet at www.a-powerusa.com/docs/APE8990-3.pdf .
