Hi,
will be possible to trigger a reset cycle from the RSTEXT pin? I need to trigger a MCU reset (connected to the TPS65381) from a secondary standby MCU. This is for a Dual Modular Redundancy architecture.
Thanks,
Jarno

Jarno,
RSTEXT pin is used to set the Reset delay extension time. If the pin is connected to 0 Ohms the delay time 1.4ms and if the pin is connected to 22k ohms, the delay time is 4.5ms.
If you need to reset the MCU, you will need to externally trigger NRES pin.

Jay
