8.1 Overview

The TPS22995H-Q1 is a 5.5-V, 3-A load switch in a 6-pin SOT-23 package. To reduce voltage drop for low voltage and high-current rails, the device implements a low-resistance, 19-mΩ N-channel MOSFET, which reduces the drop-out voltage through the device.

The device has a configurable slew rate, which helps reduce or eliminate power supply droop because of large inrush currents. The slew rate can be configured by connecting a resistor to ground to the RT pin. The TPS22995H-Q1 also integrates a Quick Output Discharge circuit that is activated when the switch is turned off, pulling the output voltage down to a known 0-V state.

TPS22995H-Q1 increases circuit robustness by integrating tolerance to high humidity environments. When the timing pin (RT) is affected by high humidity, timing is expected to stay within +/–20%. Additionally, if the device experiences a 100-kΩ short from any pin to GND or power, the device continues to function.
