MIC2012BM

Product Overview

Category: Integrated Circuit (IC)

Use: The MIC2012BM is a voltage supervisor IC that monitors the power supply voltage of electronic devices and provides a reset signal when the voltage falls below a certain threshold. It ensures proper operation of the device by preventing it from operating in an undervoltage condition.

Characteristics: - Monitors power supply voltage - Provides reset signal - Prevents undervoltage operation

Package: The MIC2012BM is available in a small outline integrated circuit (SOIC) package.

Essence: The essence of the MIC2012BM is to monitor the power supply voltage and provide a reset signal to ensure proper device operation.

Packaging/Quantity: The MIC2012BM is typically packaged in reels or tubes, with a quantity of 2500 units per reel/tube.

Specifications

The specifications of the MIC2012BM are as follows:

• Supply Voltage Range: 1.8V to 5.5V
• Reset Threshold Voltage: Adjustable from 1.2V to 4.6V
• Reset Timeout Period: Adjustable from 1ms to 640ms
• Quiescent Current: 10µA (typical)

Pin Configuration

The MIC2012BM has the following pin configuration:

1. VCC: Power supply voltage input
2. GND: Ground reference
3. MR: Manual reset input
4. RESET: Reset output

Functional Features

The functional features of the MIC2012BM include:

• Undervoltage detection: Monitors the power supply voltage and detects when it falls below the set threshold.
• Reset signal generation: Provides a reset signal to the device when an undervoltage condition is detected.
• Adjustable parameters: The reset threshold voltage and timeout period can be adjusted to suit specific application requirements.
• Manual reset input: Allows for a manual reset signal to be applied, overriding the automatic reset function.

Advantages and Disadvantages

Advantages: - Ensures proper device operation by preventing undervoltage conditions. - Adjustable parameters provide flexibility for different applications. - Small package size allows for space-saving designs.

Disadvantages: - Limited to monitoring power supply voltage and providing reset signals. Does not offer additional functionality.

Working Principles

The MIC2012BM works by continuously monitoring the power supply voltage. When the voltage falls below the set threshold, it triggers the reset output, signaling an undervoltage condition. The reset output remains active until the voltage rises above the threshold or a manual reset signal is applied.

Application Field Plans

The MIC2012BM can be used in various electronic devices that require reliable power supply monitoring and reset functionality. Some potential application fields include:

1. Microcontrollers: Ensuring proper operation of microcontrollers by preventing undervoltage conditions that could lead to data corruption or system instability.
2. Industrial Control Systems: Monitoring power supply voltage in industrial control systems to prevent malfunctions and ensure safe operation.
3. Automotive Electronics: Providing reset signals in automotive electronics to maintain stable operation and prevent damage due to undervoltage conditions.

Alternative Models

Some alternative models to the MIC2012BM include:

1. MAX823: Voltage supervisor IC with adjustable reset threshold and timeout period.
2. LTC2917: Precision voltage monitor with programmable reset threshold and timeout period.
3. TPS3808: Ultra-low quiescent current voltage supervisor with fixed reset threshold.

These alternative models offer similar functionality and can be considered based on specific application requirements.
