The TPS22996 is a 5.5V, dual-channel, 14m? (typical) RON load switch in a 8-pin DRL package. Each channel can support a maximum continuous current of 4A and is controlled by an on and off GPIO-compatible input. To reduce the voltage drop in high current rails, the device implements N-channel MOSFETs. Note that the ON pins must be connected and cannot be left floating. The device has a configurable slew rate for applications that require specific rise-time, which controls the inrush current. By controlling the inrush current, power supply sag can be reduced during turnon. Furthermore, the slew rate is proportional to the series resistor used on the ONx pin. See Section 8.3.6 to determine the correct resistor value for a desired rise time.
The internal circuitry is powered by the VBIAS pin, which supports voltages from 2.5V to 5.5V. This circuitry includes the charge pump, QOD (optional), and control logic. When a voltage is applied to VBIAS, and the ONX pins transition to a low state, the QOD functionality is activated. This connects VOUTX to ground through the on-chip resistor. The typical pulldown resistance (RPD) is 230?.
During the off state, the device prevents downstream circuits from pulling high standby current from the supply. The integrated control logic, driver, power supply, and output discharge FET eliminates the need for any external components, reducing solution size and bill of materials (BOM) count.
