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, keeping 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.
