TPS3806J20 TPS3806I33
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, keeping RESET and RSTSENSE active as long as VDD and LSENSE remain below the threshold voltage, VIT.
