9.3.2 Adjustable Quick Output Discharge

The TPS22992x device includes a QOD feature that can be configured in one of three ways:

  • QOD pin shorted to VOUT pin. Using this method, the discharge rate after the switch becomes disabled is controlled with the value of the internal resistance RQOD. The value of this resistance is listed in the Electrical Characteristics table.
  • QOD pin connected to VOUT pin using an external resistor REXT. After the switch becomes disabled, the discharge rate is controlled by the value of the total resistance of the QOD.
  • QOD pin is unused and left floating. Using this method, there is no quick output discharge functionality, and the output remains floating after the switch is disabled.

Fall time is dependent on the strength of the configured pulldown resistance on the output.
