概述

Description

TPS3619-33DGK is a Texas Instruments fixed-threshold voltage supervisor for 3.3 V systems. It continuously monitors VDD and provides a reset signal to a microcontroller or digital logic to ensure proper startup and brown-out protection. The “-33” denotes a fixed 3.3-V threshold. The DGK suffix indicates the 8-pin VSSOP package variant.
Key points:
- Fixed 3.3 V threshold; suitable for 3.3-V logic domains.
- Produces a clean reset output when VDD is below threshold or during power-up, and releases it once the supply is stable.
- Tiny, low quiescent current device ideal for MCU/SoC reset and brown-out protection.
- 8-pin device in a TI DGK package; typical operating range and exact timing/hold features are specified in the datasheet.
Use it to reliably reset microcontrollers during power-up/down or supply sag in 3.3-V systems. For exact electrical specs and timing, consult the TPS3619-33 datasheet.

Features

Here are the typical features of TPS3619-33DGK (3.3-V fixed-threshold supervisor in an 8-pin DGK package):
- Fixed 3.3-V reset threshold for MCU supervision
- Active-low RESET# output to reset microcontrollers
- Manual reset input (push-button) for external reset
- Power-on reset (POR) with deterministic reset on startup
- Low quiescent current in normal operation
- Fast reset assertion after undervoltage or power-up
- 8-pin VSSOP package (DGK)
- Extended operating temperature range (industrial-grade)
- Suitable for space-constrained applications requiring simple, software-free reset monitoring
Note: For exact electrical specs ( voltages, currents, timing, and tolerances), please refer to the official datasheet.

Package

8-pin VSSOP (Very Small Outline Package), specifically VSSOP-8 (package code DGK).

Pinout

- Pin count: 8 pins (DGK package, VSSOP-8).
- Function: TI TPS3619-33DGK is an 8-pin voltage supervisor/reset circuit with a fixed 3.3 V threshold. It monitors Vcc and provides an active-low, open-drain reset output; includes a manual reset input to force a reset (typically active-low).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits.

Application

TPS3619-33DGK is a 3.3V voltage supervisor used for reset generation. Common application areas include:
- 3.3V microcontroller/processor reset supervision
- Power-on reset and brown-out protection for MCU, DSP, FPGA, and memories
- Reset generation for portable and battery-powered devices (low quiescent current)
- System supervision in consumer electronics, industrial equipment, and data-logging systems
- Timing-critical reset control after power-up/down in embedded designs
