Hello,

Does anyone know the accuracy of the UCC2946D Watchdog timeout and reset pulse width?

Thanks,

    Hello Wanjeri,

    I am not entirely sure what you mean.  The watchdog timeout period and the reset period are determined by C_wp and the T_rp capacitors. The Electrical Characteristics table (of the data sheet) gives min/max tolerances for these periods (Watchdog period and Reset period) for the case where both of the capacitors are 64nF.  I assume that the inaccuracies (shown in the table) are due to the inaccuracy of the current source that charges the capacitors.

    Regards
