POST OFFICE BOX 655303

Hysteresis 3.3-V/Adjustable and

2-V/Adjustable

description

The TPS3806 integrates two independent voltage

detectors for battery voltage monitoring. During

power-on, RESET and RSTSENSE are asserted

respectively.

The

TPS3806

device

has

a

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.
