5 Operation

Connect the VIN power supply to the J1 terminal. The input voltage range of the TPS22999EVM is 0.1 V to VBIAS – 1 V. Connect an acceptable bias voltage to TP12. The bias voltage range of TPS22999EVM is 0.1 V to 5.5 V. Note that VIN cannot be greater than VBIAS – 1 V for correct operation of the device.

External output loads can be applied to the switch by using the J2 terminal. When the ON pin is asserted high, the output of the TPS22999 is enabled. When the device is disabled, the output rail discharges through the internal quick output discharge resistance of the device.

The status of the MOSFET being fully turned on can be viewed using the power good, PG, pin. This is an open drain pin that is pulled up to VBIAS and asserted low when the output is full load ready.
