Product Overview
The TLV803 is a Texas Instruments voltage supervisor reset IC for Power_Management designs. It monitors a supply rail and drives an active-low, open-drain RESET output. The device family supports monitored supply voltage options of 2.5 V, 3 V, 3.3 V, and 5 V, with TLV803 threshold variants at 2.25 V, 2.64 V, 2.93 V, and 4.38 V typical negative-going input thresholds.
The device operates from a recommended VDD range of 1.1 V to 6 V and is characterized for -40°C to +125°C junction temperature operation. Reset timing is fixed, with a 200 ms typical power-on reset delay after VDD exceeds the threshold and a specified reset delay range of 120 ms to 280 ms when VDD is at least VIT- + 0.2 V.
In the DBZ SOT-23 3-pin package, pin 1 is GND, pin 2 is RESET, and pin 3 is VDD. The datasheet recommends a 10 kΩ to 1 MΩ pullup on RESET and a 0.1 µF ceramic bypass capacitor close to VDD. Applications include voltage rail monitoring, reset timing, undervoltage reset, and compact board-level supply supervision.
