Présentation

Description

The TPS3707-33DGNR is TI’s fixed-threshold voltage supervisor (power-on reset) with a 3.3 V trip point. It monitors Vcc and asserts its reset output whenever the supply falls below 3.3 V or during power-up/power-down transients, ensuring a clean microcontroller/system startup. It includes built-in debounce/hysteresis for noise rejection, offers very low quiescent current, and comes in TI’s compact DGNR package. Typical uses include microcontrollers, FPGAs/logic, and battery-powered or automotive applications that require a robust POR signal. For exact pinout, reset-output polarity, delay characteristics, and current consumption, check the TPS3707-33DGNR datasheet and TI product page.

Features

TPS3707‑33DGNR features (concise):
- Fixed 3.3 V threshold voltage supervisor
- Ultra-low quiescent current
- Reset output (active-low) with clean, reliable power-on reset behavior
- Wide operating voltage range (approximately 1.8–5.5 V)
- Industrial temperature range (typical -40°C to 125°C)
- Small 5‑pin package (DGNR, SOT-23 style); RoHS-compliant and available in tape & reel
- Ideal for MCU reset and brown-out protection, ensuring proper microcontroller startup/shutdown sequences
Note: For exact timing, accuracy, and electrical characteristics, refer to the TPS3707‑33DGNR datasheet.

Pinout

- Pin count: 8 pins (VSSOP-8, DGNR RoHS package)
- Function: 3.3 V threshold voltage supervisor/reset generator. It monitors Vcc and outputs an active-low reset signal to a microcontroller/microprocessor during power-up/power-down to ensure proper reset state.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing ICs; one of the world’s largest semiconductor manufacturers, headquartered in Dallas, Texas.

Application

TPS3707-33DGNR is a 3.3-V voltage supervisor/reset IC. Primary applications:
- Microcontroller and digital-logic reset supervision for 3.3-V systems
- Power-on reset and brown-out protection during power cycles
- Battery-powered/portable devices, IoT sensors, wearables, and consumer electronics
- Any 3.3-V design needing reliable, fast reset during power-up/power-down
- Compact, low-power reset solution for embedded systems in space-constrained applications
(Provides deterministic reset without needing external components.)

Package

8-pin VSSOP (Very‑Small‑Outline Package). The DGNR suffix designates the VSSOP‑8 package (RoHS).
