UNISONIC TECHNOLOGIES CO., LTD ULS5422 Preliminary SINGLE-CHANNEL, ULTRA-Low RESISTANCE LOAD SWITCH  DESCRIPTION The UTC ULS5422 device is a small, ultra-low RON, single-channel load switch with controlled turnon. The device contains an N-channel MOSFET that can operate over an input voltage range of 0.8V to 5.5V and can support a maximum continuous current of 4A. The switch is controlled by an on/off input (ON), which can interface directly with low-voltage control signals. In the UTC ULS5422, a 225Ω pulldown resistor is added for quick output discharge when the switch is turned off. The UTC ULS5422 is available in a small, space-saving 2mm × 2mm 8pin WSON package (DSG) with integrated thermal pad allowing for high power dissipation.
