Overview
The TPV8349x is a family of supervisory circuits. The SENSE pin features a high-impedance input, enabling different voltage monitoring requirements to be met by configuring external resistors. Asserting an active low/active high open-drain or push-pull RESET/RESET output when the voltage of the sense pin drops below a fixed threshold or when the enable pin ENABLE/ENABLE is logic high/low. The RESET/RESET output remains low/high for the user-adjusted delay time by the external capacitor after the sense voltage returns above the fixed threshold with a hysteresis, and the enable PIN ENABLE/ENABLE is logic high/low.
The threshold voltage of the TPV8349x device can achieve 1% accuracy. The delay time can be set to 40 μs to 6.2 s by connecting the external capacitor to the CT pin. The TPV8349x family has a very low typical quiescent current of 600 nA.
The TPV8349x is available in the DFN1.5x1-6 package. Its operating temperature range is from −40°C to +125°C.
