Package and Quantity

The MCP102T-240E/TT is packaged in a SOT-23 package. It is typically sold in reels containing a quantity of 3000 units per reel.

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Reset Threshold Voltage: 2.4V
• Reset Timeout Period: 140ms (typical)
• Quiescent Current: 5µA (typical)
• Operating Temperature Range: -40°C to +125°C

Pin Configuration

The MCP102T-240E/TT has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that provides a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Voltage Monitoring: The MCP102T-240E/TT continuously monitors the input voltage and compares it with the preset threshold voltage.
• Reset Generation: When the monitored voltage drops below the threshold, the MCP102T-240E/TT generates a reset signal to initiate a system reset.
• Reset Timeout: The IC includes an internal timer that ensures the reset signal remains active for a specific period (140ms typical) after the voltage rises above the threshold.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring.
• Low power consumption.
• Wide operating voltage range.
• Compact package size.
• Suitable for battery-powered applications.

Disadvantages

• Limited reset timeout period.
• Single threshold voltage option.

Working Principles

The MCP102T-240E/TT operates by comparing the input voltage with the preset threshold voltage. When the input voltage falls below the threshold, the IC generates a reset signal. This signal remains active for a specific period, even if the voltage rises above the threshold during this time. Once the timeout period elapses, the reset signal is deactivated.

Application Field Plans

The MCP102T-240E/TT can be used in various applications, including: 1. Microcontrollers and microprocessors. 2. Power management systems. 3. Battery-powered devices. 4. Industrial control systems. 5. Automotive electronics. 6. Home automation systems.
