MCP111T-290E/LB

Product Overview

Category

The MCP111T-290E/LB belongs to the category of voltage supervisors and monitors.

Use

It is used to monitor the power supply voltage and provide a reset signal to the microcontroller in case of an under-voltage condition.

Characteristics

• Package: SOT-23-3
• Essence: Voltage supervisor with manual reset input
• Packaging/Quantity: Available in tape and reel packaging, quantity varies by supplier

Specifications

• Input Voltage Range: 0.7V to 5.5V
• Reset Threshold Voltage: 2.93V
• Manual Reset Input: Active-low input for external reset control
• Operating Temperature Range: -40°C to 125°C

Detailed Pin Configuration

1. VDD (Input voltage)
2. GND (Ground)
3. MR (Manual reset input)

Functional Features

• Monitors the input voltage and asserts a reset signal when the voltage falls below the threshold
• Manual reset input allows external control over the reset function
• Low quiescent current for minimal power consumption

Advantages and Disadvantages

Advantages

• Wide input voltage range
• Small package size
• Low power consumption

Disadvantages

• Limited to monitoring single power supply voltage

Working Principles

The MCP111T-290E/LB operates by comparing the input voltage to the preset threshold. When the input voltage falls below the threshold, the device asserts a reset signal to the connected microcontroller, ensuring proper operation under varying voltage conditions.

Detailed Application Field Plans

The MCP111T-290E/LB is commonly used in embedded systems, IoT devices, and battery-powered applications where maintaining stable operation during voltage fluctuations is critical. It is also suitable for use in automotive electronics and industrial control systems.

Detailed and Complete Alternative Models

• MCP111T-195E/LB: Similar voltage supervisor with a lower reset threshold
• MCP111T-315E/LB: Voltage supervisor with a higher reset threshold for different voltage monitoring requirements

This completes the entry for the MCP111T-290E/LB, providing comprehensive information about its category, use, characteristics, specifications, pin configuration, functional features, advantages and disadvantages, working principles, application field plans, and alternative models.
