TPS3838 Datasheet Nano Power Voltage Supervisor

Manufacturer: Texas Instruments

Overview: Product Folder Order Now Technical Documents Tools & Software Support & munity TPS3836, TPS3837, TPS3838 SLVS292F – JUNE 2000 – REVISED SEPTEMBER 2019 TPS383x Nano Power Voltage Supervisor With Selectable Reset Delay.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TPS3836, TPS3837, and TPS3838 device families of supervisory circuits provide circuit initialization and timing supervision, primarily for digital signal processors (DSP) and processor-based systems.

During power-on, RESET is asserted when the supply voltage VDD bees higher than 1.1 V.

Thereafter, the supervisory circuit monitors VDD and keeps the RESET output active as long as VDD remains below the threshold voltage of VIT.

Key Features

  • 1 Supply current: 220 nA (typical).
  • Precision supply voltage supervision range: 1.8 V, 2.5 V, 3.0 V, and 3.3 V.
  • Power-on reset generator with selectable delay time: 10 ms or 200 ms.
  • Push and pull RESET output (TPS3836), Push and pull RESET output (TPS3837), or opendrain RESET output (TPS3838).
  • Manual reset.
  • 5-pin SOT23 and 2-mm × 2-mm, 6-pin SON packages.
  • Temperature range:.
  • 40°C to 85°C 2.
