SLVS393A – JULY 2001 – REVISED NOVEMBER 2004
Dual Voltage Detector with Adjustable Hysteresis
FEATURES
Dual Voltage Detector With Adjustable
Hysteresis 3.3-V/Adjustable and
2-V/Adjustable
Assured Reset at VDD = 0.8 V
Supply Current: 3 µA Typical at VDD = 3.3 V
Independent Open-Drain Reset Outputs
Temperature Range: -40°C to +85°C
6-Pin SOT-23 Package
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, keep-
ing 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 pack-
age. The TPS3806 device is characterized for oper-
ation over a temperature range of -40°C to +85°C.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated
circuits be handled with appropriate precautions. Failure to observe proper handling and installation
procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to GND. For reliable operation, the device must not be continuously operated at 7 V for more than
t = 1000 h.
