APPLICATIONS Mobile phones Digital cameras and audio devices Portable and battery-powered equipment GENERAL DESCRIPTION The ADP197 is a high-side load switch designed for operation The ADP197-02 incorporates an internal quick output between 1.8 V and 5.5 V. This load switch provides power domain discharge (QOD) circuit to discharge the output capacitance isolation, which helps extend battery operation. The device when the ADP197-02 output is disabled contains a low on-resistance, N-channel MOSFET that supports In addition to operating performance, the ADP197 WLCSP more than 3 A of continuous current and minimizes power loss. package occupies minimal printed circuit board (PCB) space The low 18 A quiescent current and ultralow shutdown current 2 with an area of less than 1.5 mm and a height of 0.60 mm. make the ADP197 ideal for battery-operated portable equipment. The ADP197 is available in an ultrasmall 1.0 mm 1.5 mm, The built-in level shifter for enable logic makes the ADP197 0.5 mm pitch, 6-ball WLCSP and a 2.0 mm 2.0 mm compatible with many processors and GPIO controllers. 0.55 mm, 0.65 mm pitch, 6-lead LFCSP. Overtemperature protection circuitry activates if the junction temperature exceeds 125C, thereby protecting itself and downstream circuits from potential damage. Rev.
