Other Parts Discussed in Thread: TPS3435

Hello forum,

I wanted to ask about the TPS3435 watchdog, specifically the TPS3435AFACADDFRQ1 version. Could you please indicate how it can be disabled? I'm not entirely clear on this.

Thank you

    Hi Manuel,

    The TPS3435AFACADDFRQ1 (A pinout option) can be disabled by connection the CWD pin to either ground or a capacitance value greater than recommended (>>1uF).

    This information can be found under section 8.3.1.2 Watchdog Enable Disable Operation:

     

    Thanks,
