2.93V threshold supervisor for 3.3V rails
The TPS3705-33DGN is a single-channel voltage supervisor from Texas Instruments, monitoring a 3.3V supply rail with a threshold of 2.93V. When the monitored voltage drops below this threshold, the reset output (Active Low, Push-Pull) asserts and holds for a minimum of 140ms after the supply recovers. This part belongs to the Simple Reset/Power-On Reset category within the Power Management (PMIC / Gate Driver) line.
Industrial temp range and package
The base product number is TPS3705; other threshold variants in the same family share the same pinout, so a BOM change to a different voltage option is a direct drop-in if the threshold requirement shifts.
