Essence

The essence of MIC809-5SU-TR lies in its ability to monitor the supply voltage and generate a reset signal when the voltage falls below a certain threshold.

Packaging/Quantity

This product is typically sold in reels containing 3000 units per reel.

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Reset Threshold Voltage: 4.63V
• Reset Timeout Period: 140ms
• Quiescent Current: 1µA (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

MIC809-5SU-TR has five pins arranged as follows:

1. VCC: Power supply input
2. GND: Ground reference
3. MR: Manual reset input (active low)
4. RESET: Reset output (active low)
5. NC: No connection (unused pin)

Functional Features

• Monitors the supply voltage continuously
• Generates a reset signal when the voltage drops below the threshold
• Reset signal remains active until the voltage rises above the threshold or a timeout period elapses
• Manual reset input allows for external reset control

Advantages and Disadvantages

Advantages

• Low power consumption makes it suitable for battery-powered devices
• Wide operating voltage range provides flexibility in various applications
• Small package size saves board space
• High accuracy ensures reliable voltage monitoring

Disadvantages

• Reset output signal is active low, which may require additional circuitry for compatibility with certain systems
• Limited timeout period may not be suitable for applications requiring longer reset times

Working Principles

MIC809-5SU-TR operates by comparing the supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the internal circuit triggers a reset signal. This signal remains active until the voltage rises above the threshold or the timeout period elapses. The manual reset input allows for external control of the reset function.
