Description for the TPS3806I33-Q1
The TPS3806I33-Q1 integrates two independent voltage detectors for battery
voltage monitoring. During power on, the device asserts RESET and
RSTSENSE when supply voltage VDD or the voltage at
the LSENSE input becomes 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 rises above the threshold voltage VIT, the device deasserts
RESET or RSTSENSE, respectively. The TPS3806I33-Q1
device has a fixed-sense threshold voltage VIT set by an internal voltage
divider at VDD and an adjustable second-LSENSE input. In addition, one can
set an upper voltage threshold at HSENSE to allow a wide adjustable
hysteresis window.
The devices are available in a 6-pin SOT-23 package. Characterization of the TPS3806I33-Q1 device is for operation over a temperature range of –40°C to 125°C.
