The TPS3806 integrates two independent voltage detectors for battery voltage monitoring. During power-on, RESET\ and RSTSENSE\ are asserted when supply voltage V_DD or the voltage at LSENSE input become higher than 0.8 V. Thereafter, the supervisory circuit monitors V_DD and LSENSE, keeping RESET\ and RSTSENSE\ active as long as V_DD and LSENSE remain below the threshold voltage V_IT. As soon as V_DD or LSENSE rise above the threshold voltage V_IT, RESET\ or RSTSENSE\ is deasserted, respectively. The TPS3806 device has a fixed-sense threshold voltage V_IT set by an internal voltage divider at V_DD and an adjustable second-LSENSE input. In addition, an upper voltage threshold can be set at HSENSE to allow a wide adjustable hysteresis window.

The devices are available in a 6-pin SOT-23 package. The TPS3806 device is characterized for operation over a temperature range of –40°C to 85°C.
