Dual Voltage Detector with Adjustable Hysteresis
Dual Voltage Detector With Adjustable
The TPS3806 integrates two independent voltage
Hysteresis 3.3-V/Adjustable and
detectors for battery voltage monitoring. During
2-V/Adjustable
power-on, RESET and RSTSENSE are asserted
when supply voltage VDD or the voltage at LSENSE
Assured Reset at VDD = 0.8 V
input become higher than 0.8 V. Thereafter, the
Supply Current: 3 A Typical at VDD = 3.3 V
supervisory circuit monitors VDD and LSENSE, keep-
Independent Open-Drain Reset Outputs
ing RESET and RSTSENSE active as long as VDD
and LSENSE remain below the threshold voltage, VIT.
Temperature Range: -40
°C to +85°C
As soon as VDD or LSENSE rise above the threshold
6-Pin SOT-23 Package
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 pack-
age. The TPS3806 device is characterized for oper-
ation over a temperature range of -40
°C to +85°C.
