High-Side Load Switch
ADP199

GENERAL DESCRIPTION

The ADP199 is a high-side load switch designed for opera­tion between 0.9 V to 3.6 V. A load switch provides power domain isolation, thereby helping to keep subsystems isolated and powered independently, and enabling reduced power consumption.
The ADP199 contains a low on-resistance, N-channel MOSFET to minimize power loss, and supports over 500 mA of continuous load current. The low 6 µA quiescent current and ultralow shutdown current make the ADP199 ideal for battery-operated portable equipment. The built-in level shifter for enable logic makes the ADP199 compatible with many processors and GPIO controllers.
In addition to high performance, the ADP199 occupies mini­mal printed circuit board (PCB) space with an area of less than
0.64 mm
The ADP199 is available in an ultra-small, 0.8 mm × 0.8 mm ×
0.5 mm, 4-ball, 0.4 mm pitch WLCSP.

THEORY OF OPERATION

The ADP199 is a high-side NMOS load switch controlled by an internal charge pump. The ADP199 is designed to operate with power supply voltages between 0.9 V and 3.6 V.
An internal charge pump biases the NMOS switch to achieve a relatively constant, ultralow on resistance of 40 mΩ across the entire input voltage range. The use of the internal charge pump also allows for controlled turn-on times. The switch is controlled on/off by the enable (EN) input and is capable of interfacing directly with
1.2 V logic signals.

CHARGE PUMP
AND SLEW RATE
The ADP199 is capable of 500 mA of continuous load current as long as T
is less than 85°C.
J
ESD protection structures are shown in the block diagram (see Figure 29) as Zener diodes.
The ADP199 is a low quiescent current device with a nominal 4 MΩ pull-down resistor on its enable pin (EN). The package is a space-saving 0.8 mm × 0.8 mm, 4-ball WLCSP.

ENABLE FEATURE

As shown in Figure 31, the EN pin has hysteresis built into it. This prevents on/off oscillations that can occur due to noise on the EN pin as it passes through the threshold points.
The EN pin active/inactive thresholds derive from the V
voltage;

therefore, these thresholds vary with the changing input voltage. Figure 33 shows the typical EN active/inactive thresholds when the input voltage varies from 1.1 V to 3.6 V.
