2 A load switches

4 April 2012 Power Electronics / Power Management

Vishay recently released three new single and dual 2 A load switches designed for 1,1 V to 5,5 V operation. Offering low switch on-resistance at 1,2 V for increased efficiency, the SiP32411, SiP32413 and SiP32414 feature a controlled soft turn-on slew rate of 150 s typical that limits the inrush current, providing a controlled, smoother turn-on transition that minimises switching noise.

The SiP32411 is a single switch available in both the 1,2 mm by 1,6 mm TDFN4 package and the SC70-6 package, while the SiP32413 and SiP32414 are dual switches available in the 2 x 2 mm TDFN8 package. All three devices guarantee low switch on-resistance of 66 m at 1,2 V input (105 m for the SiP32411 in the SC70-6 package), with each switch supporting over 2 A of continuous current.

The devices feature a low-voltage control logic interface that eliminates the need for extra level shifting circuitry. They offer a low quiescent current of < 1 A when disabled and 6,7 A at 1,2 V, allowing for longer on-times in battery-powered equipment. When disabled, the switches provide reverse blocking to prevent high current from flowing into the power source. The SiP32411 and SiP32414 integrate output discharge switches that enable rapid turn-off of a load circuit when the switch is disabled.

The two load switches in the SiP32413 feature reverse control logic. The device can easily be configured as a two-to-one power source, routing two power rails of different potentials to the common load point. The SiP32414 consists of two load switches of the same logic, and is ideal for loads with dual power rails.

The SiP32411, SiP32413 and SiP32414 will be used in USB, SIM, SDIO, POL, RF and Wi-Fi module load applications in wireless modems and portable devices. The devices are compliant to RoHS directive 2002/95/EC and halogen-free according to the IEC 61249-2-21 definition.
