DESCRIPTION

The TPS3806 integrates two independent voltage

detectors for battery voltage monitoring. During

power-on, RESET and RSTSENSE are asserted

when supply voltage V

input become higher than 0.8 V. Thereafter, the

= 3.3 V

supervisory circuit monitors V

ing RESET and RSTSENSE active as long as V

and LSENSE remain below the threshold voltage, V

As soon as V

voltage V

, RESET or RSTSENSE is deasserted,

respectively. The TPS3806 device has a fixed-sense

threshold voltage V

at V

and an adjustable second-LSENSE input. In

addition, an upper voltage threshold can be set at

HSENSE

hysteresis window.

The devices are available in a 6-pin SOT-23 pack-

age. The TPS3806 device is characterized for oper-

ation over a temperature range of -40 C to +85 C.
