Description

The TPS3806I33-Q1 integrates two independent voltage detectors for battery voltage monitoring. During power on, the device assertsRESETandRSTSENSEwhen supply voltage VDDor the voltage at the LSENSE input becomes higher than 0.8 V. Thereafter, the supervisory circuit monitors VDDand LSENSE, keepingRESETandRSTSENSEactive as long as VDDand LSENSE remain below the threshold voltage, VIT. As soon as VDDor LSENSE rises above the threshold voltage VIT, the device deassertsRESETorRSTSENSE, respectively. The TPS3806I33-Q1 device has a fixed-sense threshold voltage VITset by an internal voltage divider at VDDand an adjustable second-LSENSE input. In addition, one can set an upper voltage threshold at HSENSE to allow a wide adjustablehysteresis window. The devices are available in a 6-pin SOT-23 package. Characterization of the TPS3806I33-Q1 device is for operation over a temperature range of –40°C to 125°C.
