PRODUCTION DATA.
The PWRFAIL signal is generated by a voltage detector at the PWRFAIL_SNS input. The input signal is compared to a 1 V threshold (falling edge) with 5% (50 mV) hysteresis. PWRFAIL is an open drain output which is actively low when the input voltage at PWRFAIL_SNS is below the threshold.
