Description

The TPS3806 integrates two independent voltage detectors for battery voltage monitoring. During power-on, RESET\ and RSTSENSE\ are asserted when supply voltage VDDor the voltage at LSENSE input become higher than 0.8 V. Thereafter, the supervisory circuit monitors VDDand LSENSE, keeping RESET\ and RSTSENSE\ active as long as VDDand LSENSE remain below the threshold voltage VIT. As soon as VDDor LSENSE rise above the threshold voltage VIT, RESET\ or RSTSENSE\ is deasserted, respectively. The TPS3806 device has a fixed-sense threshold voltage VITset by an internal voltage divider at VDDand 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. The TPS3806 integrates two independent voltage detectors for battery voltage monitoring.
