The document describes the basic characteristics of the TPS310x, TPS311x family of supervisory circuits, including the precision supply voltage supervision range, high threshold accuracy, low supply current, RESET definition, power-on reset generator, etc.
The TPS31xx series provides precision supply‑voltage supervision for low‑power DSPs, microcontrollers and microprocessors. It monitors the supply voltage, asserts a reset when the voltage falls below a threshold, and includes a programmable delay to ensure proper system start‑up.
Typical applications include portable battery‑powered equipment, intelligent instruments, wireless communication systems, industrial equipment, computers and automotive systems. The devices are offered in a 6‑pin SOT‑23 package and operate over a temperature range of –40 °C to 85 °C.
