Protected high-side 1 A load switch has selectable current limit

24 August 2005 Power Electronics / Power Management

Vishay's new protected high-side load switch can operate under a supply voltage range of 2,4 V to 5,5 V and handle a continuous output current of 1 A, with the threshold current set by a single external resistor. The SiP4610A/B is designed for applications including load switching, battery switching, USB peripheral ports, and other power management applications in notebook computers and other portable and handheld systems. A user-defined current limit level protects the input supply voltage from excessive load currents. The SiP4610A/B has a low quiescent current of 9 μA, and reduces the supply current to less than 1 μA in shutdown mode. Providing the ability to selectively turn on and shut down various system functions, and to switch between power supply sources: the SiP4610A has an active low enable input; the SiP4610B has an active high enable input. In addition to current limit, the chips are protected by undervoltage lockout and thermal shutdown features. They come in 5-pin SC-70 and thin SOT-23 packages.
