Essence

The essence of this product lies in its ability to monitor the voltage level of an electronic system and provide a reset signal when the voltage falls below a certain threshold.

Packaging/Quantity

The MCP810T-485I/TT is typically packaged in reels containing 3000 units per reel.

Specifications

• Supply Voltage Range: 1.8V to 5.5V
• Reset Threshold Voltage: 2.93V (typical)
• Reset Threshold Accuracy: ±2.5%
• Operating Temperature Range: -40°C to +85°C
• Quiescent Current: 1.6µA (typical)

Detailed Pin Configuration

The MCP810T-485I/TT has three pins:

1. VDD: This pin is connected to the power supply voltage.
2. GND: This pin is connected to the ground.
3. RESET: This pin provides the reset signal when the voltage falls below the threshold.

Functional Features

• Voltage Monitoring: The MCP810T-485I/TT continuously monitors the supply voltage and generates a reset signal when it falls below the threshold.
• Manual Reset: The product also includes a manual reset input, allowing for external control of the reset signal.
• Power-On Reset Delay: The MCP810T-485I/TT incorporates a power-on reset delay to ensure stable operation during power-up.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows for compatibility with various electronic systems.
• Low quiescent current minimizes power consumption.
• Small package size enables use in space-constrained applications.
• RoHS compliance ensures environmental friendliness.

Disadvantages

• The reset threshold accuracy may not be suitable for applications requiring high precision.
• Limited pin configuration options may restrict certain system designs.

Working Principles

The MCP810T-485I/TT operates by comparing the supply voltage with a preset threshold. When the voltage falls below this threshold, the reset output is activated, indicating a low-voltage condition. The manual reset input provides an additional means to trigger the reset signal externally.

Detailed Application Field Plans

The MCP810T-485I/TT finds application in various fields, including but not limited to:

1. Battery-Powered Devices: Ensuring proper functioning and safe shutdown in low-voltage conditions.
2. Microcontroller Systems: Protecting sensitive microcontrollers from voltage fluctuations.
3. Industrial Control Systems: Monitoring power supply integrity in critical industrial applications.
4. Automotive Electronics: Providing reliable voltage supervision for automotive electronic systems.

Detailed and Complete Alternative Models

1. MCP809T-485I/TT: Similar to the MCP810T-485I/TT, but with a different reset threshold voltage.
2. MCP811T-485I/TT: Offers additional features such as adjustable reset threshold and watchdog timer functionality.
3. MAX809T-485I/TT: A comparable voltage supervisor from a different manufacturer.

Note: This is not an exhaustive list, and there may be other alternative models available in the market.
