General Description

The TPS382x family of supervisors provide circuit initialization and timing supervision, primarily for DSP and processor-based systems.

During power on, RESET asserts when the supply voltage VDD becomes greater than 1.1 V.

Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active low as long as VDD remains less than the threshold voltage, VIT−.

Overview

TPS3820, TPS3823, TPS3824, TPS3825, TPS3828 SLVS165N – APRIL 1998 – REVISED JULY 2022 TPS382x Voltage Monitor With Watchdog Timer.

Key Features

  • Power-on reset generator with a fixed delay time of 200 ms (TPS3823, TPS3824, TPS3825, and TPS3828) or 25 ms (TPS3820).
  • Manual reset input (TPS3820, TPS3823, TPS3825, and TPS3828).
  • Reset output available in active-low (TPS3820, TPS3823, TPS3824, and TPS3825), active-high (TPS3824 and TPS3825), and open drain (TPS3828).
  • Supply voltage supervision range: 2.5 V, 3 V, 3.3 V, 5 V.
