TPS3806I33 Overview
The TPS3806 integrates two independent voltage detectors for battery voltage monitoring. During power-on, RESET and RSTSENSE are asserted when supply voltage VDD or the voltage at LSENSE input bee higher than 0.8 V. Thereafter, the supervisory circuit monitors VDD and LSENSE, keeping RESET and RSTSENSE active as long as VDD and LSENSE remain below the threshold voltage, VIT.
