DESCRIPTION

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 become higher than 0.8 V. Thereafter, the

supervisory circuit monitors VDD and LSENSE, keep-

ing RESET and RSTSENSE active as long as VDD

and LSENSE remain below the threshold voltage, VIT.

As soon as VDD or LSENSE rise above the threshold voltage VIT, RESET or RSTSENSE is deasserted,

respectively. The TPS3806 device has a fixed-sense

threshold voltage VIT set by an internal voltage divider

at VDD 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.
