Figure 22. Functional Block Diagram
The ADP198 is a high-side PMOS load switch that is designed
for supply operation between 1.65 V and 6.5 V. The PMOS load
switch has a low on resistance of 50 mΩ at V
IN
= 3.3 V and
supports 1 A of continuous load current. The ADP198 features
low quiescent current at 2.5 μA typical using a 2.8 V supply.
The enable input incorporates a nominal 4 MΩ pull-down
resistor. SEL0 and SEL1 program the start-up time of the load
switch to reduce inrush current when the switch is turned on.
The reverse current protection circuitry prevents current from
flowing backwards through the ADP198 when the output voltage
is greater than the input voltage. A comparator senses the differ-
ence between the input and output voltages. When the difference
between the input voltage and output voltage exceeds 75 mV,
the body of the PFET is switched to VOUT and turned off or
opened. In other words, the gate is connected to VOUT.
The packaging is a space-saving 1 mm × 1 mm, 4-ball WLCSP.
The ADP198 is also available in a 2 mm × 2 mm × 0.55 mm,
0.5 mm pitch LFCSP.
