TLV809L30DBVR

Product Overview

Category: Voltage Supervisor

Use: TLV809L30DBVR is a voltage supervisor designed to monitor the power supply voltage of a system and provide a reset signal to the microcontroller or other digital devices when the voltage drops below a certain threshold.

Characteristics: - Low quiescent current - Wide operating voltage range - Adjustable reset threshold - Open-drain output - Small package size

Package: SOT-23-5

Essence: The TLV809L30DBVR is an essential component in electronic systems that require reliable power supply monitoring to ensure proper functioning and prevent data corruption or system failures.

Packaging/Quantity: The TLV809L30DBVR is typically sold in reels containing 3000 units.

Specifications

• Supply Voltage Range: 1.2V to 6.5V
• Reset Threshold Voltage: Adjustable from 2.93V to 4.63V
• Quiescent Current: 1.1µA (typical)
• Operating Temperature Range: -40°C to +85°C

Pin Configuration

The TLV809L30DBVR has a total of five pins:

1. GND: Ground connection
2. VDD: Positive supply voltage input
3. MR: Manual reset input (active-low)
4. RESET: Open-drain reset output
5. NC: No connection (leave unconnected)

Functional Features

• Power-on reset generation
• Programmable reset threshold
• Manual reset input for immediate system reset
• Open-drain reset output for easy interfacing with microcontrollers
• Low-power consumption

Advantages and Disadvantages

Advantages: - Low quiescent current helps conserve power in battery-operated devices - Wide operating voltage range allows for compatibility with various power supply configurations - Adjustable reset threshold provides flexibility in system design - Small package size enables space-saving PCB layout

Disadvantages: - Lack of built-in hysteresis may result in multiple reset signals during voltage fluctuations near the threshold - Limited number of pins may restrict additional functionality integration

Working Principles

The TLV809L30DBVR monitors the supply voltage using an internal voltage reference and comparator. When the voltage drops below the programmed threshold, the reset output is asserted low, indicating a system reset condition. The reset output remains low until the supply voltage rises above the threshold and a specified delay time elapses.
