GENERAL DESCRIPTION
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 mm
2
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.
