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 μA quiescent current and ultralow shutdown current with an area of less than 1.5 mm2 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 125°C, thereby protecting itself and downstream circuits from potential damage. Rev.

ADP197 Data Sheet TIMING ILOAD Turn-on delay is defined as the interval between the time that V exceeds the rising threshold voltage and when V rises to EN OUT ~10% of its final value. The ADP197 includes circuitry that has a typical 1 ms turn-on delay and a controlled rise time to limit the 1 C26H61m AAMPL V inrush current. As shown in Figure 29 and Figure 30, the turn- IN on delay is nearly independent of the input voltage.

For very large values of output capacitance, the RC time constant (where C is the load capacitance (C ) and R is the RDS ||R ) LOAD ON LOAD can become a factor in the rise time of the output voltage. Because RDS is much smaller than R , an adequate approximation ON LOAD for RC is RDS × C . An input or load capacitor is not ON LOAD required for the ADP197 although capacitors can be used to VOUT suppress noise on the board.
