TPS3820 - Voltage Monitor

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.

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.
  • Watchdog timer (TPS3820, TPS3823, TPS3824, and TPS3828).
  • Supply cu.
