Data Sheet 3.6 V, 500 mA Logic Controlled High-Side Load Switch ADP199 FEATURES GENERAL DESCRIPTION Constant low RDSON of 40 mΩ over input voltage range Low input voltage range: 0.9 V to 3.6 V 500 mA continuous operating current at 85°C 1.2 V logic compatible enable input Low 6 μA quiescent current, independent of load current Ultralow shutdown current: <100 nA Ultrasmall 0.8 mm × 0.8 mm × 0.5 mm, 4-ball, 0.4 mm pitch WLCSP 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. APPLICATIONS Low operating voltage processors Mobile phones Digital cameras and audio devices Portable and battery-powered equipment Optical XMT/RCVR modules In addition to high performance, the ADP199 occupies minimal printed circuit board (PCB) space with an area of less than 0.64 mm2 and a height of 0.50 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.

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. The ADP199 is capable of 500 mA of continuous load current as long as TJ is less than 85°C. 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.

Ground Current vs. Input Voltage, Different Load Current ENABLE FEATURE The ADP199 uses the EN input to enable and disable the VOUT output. As shown in Figure 31, when a rising voltage (VEN) on the EN pin crosses the active threshold, VOUT turns on. When a falling voltage (VEN) on the EN pin crosses the inactive threshold, VOUT turns off. 3.5 VOUT AT 3.3V 3.0 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 VIN 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. 2.5 EN RISE EN FALL 2.0 1.5 1.0 2.5 0.5 0 1.0 1.5 1.5 2.0 2.5 3.0 3.5 INPUT VOLTAGE (V) 1.0 09672-033 2.0 Figure 33.

Figure 30 shows the typical ground current when VEN = VIN, and varies from 1.1 V to 3.6 V. Turn-on delay is defined as the interval between the time that VEN exceeds the rising threshold voltage and when VOUT rises to ~10% of its final value. The ADP199 includes circuitry that has a typical 1 ms turn-on delay, and a controlled rise time to limit the VIN inrush current. As shown in Figure 34 and Figure 35, the turnon delay is nearly independent of the input voltage.

Typical Rise Time and Inrush Current, CLOAD = 100 μF, VIN = 3.6 V, ILOAD =100 mA The rise time is defined as the time it takes the output voltage to rise from 10% to 90% of VOUT reaching its final value. It is dependent on the rise time of the internal charge pump. The turn-off time is defined as the time it takes for the output voltage to fall from 90% to 10% of VOUT reaching its final value. The turn-off time is also dependent on the RC time constant of the output capacitance and load resistance. Figure 38 shows the typical turn-off time with VIN = 1.8 V, COUT = 1 μF, and RLOAD = 18 Ω. For very large values of output capacitance, the RC time constant (where C is the load capacitance (CLOAD) and R is the RDSON||RLOAD) can become a factor in the rise time of the output voltage. Because RDSON is much smaller than RLOAD, an adequate approximation for RC is RDSON × CLOAD. An input or load capacitor is not required for the ADP199 although capacitors can be used to suppress noise on the board.
