Load switch ICs series with ultra-low power consumption extends battery lifetime

Littelfuse, Inc. offers its latest release of five versatile load switch devices in the Protection ICs product line.

These new Load Switch ICs are ultra-efficient, 2A and 4A-rated load switches with integrated TRCB and slew rate control. The best-in-class efficiency makes them excellent for mobile and wearable consumer electronics. They support the industry's lowest quiescent current (IQ), low RON, and shutdown current (ISD), enabling designers to reduce parasitic leakage current, improve system efficiency, and increase overall battery lifetime.

The latest load switch ICs are excellent for use in various electronics designs, including Handheld devices, Wearables, IoT, SSD storage, Building automation, and Consumer electronics.

"The new Load Switch IC Series supports an extended battery lifetime for mobile and wearable products by providing low power consumption and power savings with easy-to-power on/off control," said Bernie Hsieh, assistant product manager of the Protection Semiconductor Business team at Littelfuse. "Their package's chip-scale form factor provides space savings while integrating multiple functions, such as slew rate control, true reverse current blocking, and quick output discharging."

These ICs offer key benefits over previous solutions, including power-saving results in a significantly longer battery lifetime. They employ a chip-scale package (with WLCSP) to replace discrete circuits with multiple functional integrations such as power MOSFET, reverse diode, discharge MOSFET, passive components, etc. The chip-scale-size form factor also greatly lessens PCB space needs.
