MIC810MU-TR

Product Overview

Category

MIC810MU-TR belongs to the category of integrated circuits (ICs).

Use

This product is commonly used in electronic devices for voltage monitoring and reset functions.

Characteristics

• Voltage monitoring: MIC810MU-TR monitors the supply voltage level and provides a reset signal when it falls below a specified threshold.
• Reset function: It ensures that the microcontroller or other digital circuitry starts operating from a known state after power-up or brownout conditions.
• Low power consumption: MIC810MU-TR is designed to consume minimal power, making it suitable for battery-powered applications.
• Small package size: This IC comes in a compact SOT-23 package, allowing for space-efficient designs.
• Wide operating voltage range: It can operate within a wide voltage range, typically from 1.6V to 5.5V.

Package and Quantity

MIC810MU-TR is available in a SOT-23 package. It is commonly sold in reels containing a quantity of 3000 units.

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Reset Threshold Voltage: 2.93V (typical)
• Reset Timeout Period: 140ms (typical)
• Quiescent Current: 1µA (typical)
• Operating Temperature Range: -40°C to +85°C

Pin Configuration

MIC810MU-TR has three pins:

1. VCC: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin for the reset signal.

Functional Features

• Undervoltage detection: MIC810MU-TR continuously monitors the supply voltage and detects when it drops below the specified threshold.
• Reset signal generation: When an undervoltage condition is detected, the IC generates a reset signal to ensure a controlled restart of the microcontroller or digital circuitry.
• Reset timeout: The reset signal remains active for a specific period (reset timeout) after the supply voltage rises above the threshold, allowing sufficient time for stable operation to be established.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality.
• Low power consumption.
• Compact package size.
• Wide operating voltage range.
• Suitable for battery-powered applications.

Disadvantages

• Limited reset timeout period may not be suitable for certain applications requiring longer stabilization times.
• Lack of additional features such as adjustable reset threshold or programmable timeout.

Working Principles

MIC810MU-TR operates by comparing the supply voltage with a fixed threshold. When the voltage drops below this threshold, the IC triggers the reset signal. The reset signal remains active for a specific period after the voltage rises above the threshold, ensuring a controlled restart of the system.

Application Field Plans

MIC810MU-TR finds applications in various electronic devices where reliable voltage monitoring and reset functionality are required. Some potential application fields include: - Microcontrollers and microprocessors - Embedded systems - Power management circuits - Battery-powered devices - Industrial control systems
