description

typical operating circuit

The TPS3806 integrates two independent voltage

detectors for battery voltage monitoring. During

power-on, RESET and RSTSENSE are asserted

when supply voltage V

or the voltage at

LSENSE input become higher than 0.8 V.

Thereafter, the supervisory circuit monitors V

respectively. The TPS3806 device has

fixed-sense threshold voltage V set by an

internal voltage divider at V

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.
