ADI ADP197ACPZN-02-R7

The ADP197 is a high-side load switch designed for operation between 1.8 V and 5.5 V. This load switch provides power domain isolation, which helps extend battery operation. The device contains a low on-resistance, N-channel MOSFET that supports more than 3 A of continuous current and minimizes power loss. The low 18 μA quiescent current and ultralow shutdown current make the ADP197 ideal for battery-operated portable equipment. The built-in level shifter for enable logic makes the ADP197 compatible with many processors and GPIO controllers. Overtemperature protection circuitry activates if the junction temperature exceeds 125°C, thereby protecting itself and downstream circuits from potential damage. The ADP197-02 incorporates an internal quick output discharge (QOD) circuit to discharge the output capacitance when the ADP197-02 output is disabled. In addition to operating performance, the ADP197 WLCSP package occupies minimal printed circuit board (PCB) space with an area of less than 1.5 mm² and a height of 0.60 mm. The ADP197 is available in an ultrasmall 1.0 mm×1.5 mm, 0.5 mm pitch, 6-ball WLCSP and a 2.0 mm×2.0 mm×0.55 mm, 0.65 mm pitch, 6-lead LFCSP.
