This document is the TPS3705-30, TPS3705-33, TPS3705-50 TPS3707-25, TPS3707-30, TPS3707-33, TPS3707-50 user manual, introduces the features and characteristics of the product.
The TPS3705 and TPS3707 families are microprocessor supply‑voltage supervisors that provide power‑on reset, voltage monitoring, and optional watchdog functions for DSP and processor‑based systems. They operate from 2.5 V to 5 V and include a manual reset input (MR) and a power‑fail comparator.
These devices are offered in MSOP‑8 and SO‑8 packages, support operation from –40 °C to 85 °C, and feature a fixed 200 ms reset delay with a 1.6 s watchdog timeout (TPS3705 only). The data sheet includes electrical characteristics, absolute maximum ratings, and timing diagrams for design reference.
