Overview

Description

TPS3707-33DGNR is a fixed-threshold voltage supervisor (reset generator) from Texas Instruments. It monitors Vcc and asserts a reset output whenever the supply falls below its fixed 3.3-V threshold or during power-up until the voltage stabilizes. The “-33” denotes the 3.3-V threshold, and the “DGNR” suffix indicates a small, lead-free, RoHS-compliant package.
Key points:
- Fixed 3.3-V reset supervision for microcontrollers and digital ICs
- Ultra-low quiescent current for battery-powered designs
- Fast, clean reset output with power-on reset behavior
- Typically requires no external components
Common uses include ensuring proper MCU startup/shutdown, brown-out protection, and reliable reset during power events in embedded systems.

Features

TPS3707-33DGNR features (concise):
- Fixed 3.3-V voltage detector with POR for microcontrollers
- Ultra-low quiescent current (microamp-range) in normal operation
- Open-drain/reset output (requires pull-up)
- Internal reset timeout—no external components needed
- Wide operating temperature: -40°C to 125°C
- 8-pin VSSOP package (DGNR), RoHS-compliant, Tape & Reel
- Suitable for battery-powered and space-constrained applications
Note: Provides a robust reset signal when Vcc falls below 3.3 V and releases after Vcc stabilizes.

Package

TPS3707-33DGNR uses an 8-pin VSSOP package (VSSOP-8). DGNR denotes this package/reel option (RoHS, TF/tape and reel).

Pinout

- Pin count: 3 pins (VCC, GND, RESET).
- Function: TPS3707-33DGNR is a 3.3 V voltage supervisor that monitors the supply and asserts a reset output when VCC falls below 3.3 V, releasing when the voltage is above the threshold (used to ensure proper MCU startup/shutdown).

Manufacturer

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

Application

- Reset supervision for 3.3V MCUs/digital ICs
- Power-on reset and brown-out protection for 3.3V rails
- Embedded systems, IoT, portable electronics, wearables
- Battery-powered devices with low quiescent current
- Any system needing reliable 3.3V monitoring and MCU reset on power-up/down

Equivalent

Equivalent parts (3.3 V threshold) from other vendors:
- TI: TPS3890-33, TPS3807-33
- Analog Devices: ADM803-3.3, ADM803A-3.3
- Maxim Integrated: MAX809-3.3, MAX810-3.3
- Microchip: MCP131-3.3, MCP132-3.3
Note: check pinout, reset delay, and supply tolerance in datasheets for exact cross-replacement.
