TLV803ED29DBZR

Supervisors Overview

The TLV803ED29DBZR is a low-power voltage supervisor from the Texas Instruments TLV803E series, designed for monitoring single-channel input voltages. It operates within a supply voltage range of 1.7 V to 6 V and features a fixed threshold voltage of 2.93 V with an accuracy of 0.5%. The device provides an active-low, open-drain output and includes a reset delay time of 400 ms. It draws a typical static current of 400 nA and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a compact SOT-23-3 format, it lacks manual reset, watchdog timer, or battery backup switching capabilities.
