7.3.1.6 RESET Function
During adaptive voltage scaling (AVS) operation, the voltage may become falsely adjusted to be out of ASIC operating range. The RESET function returns the voltage to the VBOOT voltage. When the voltage is out of ASIC operating range, the ASIC issues a RESET signal to the TPS53681 device, as shown in Figure 11. The device senses this signal and after a delay of greater than 1 µs, it sets an internal RESET_FAULT signal and sets VOUT_COMMAND to VBOOT. The device pulls the output voltage to the VBOOT level with the slew rate set by VOUT_TRANSITION_RATE command, as shown in Figure 12.
When the RESET pin signal goes high, the internal RESET_FAULT signal goes low.
