Package

The MAX819MCPA+ is available in a small outline package (SOP) with a specified pin configuration.

Essence

The essence of MAX819MCPA+ lies in its ability to monitor voltage levels and provide a reset signal when necessary, ensuring reliable operation of electronic systems.

Packaging/Quantity

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

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Reset Threshold Voltage: Adjustable from 1.2V to 4.63V
• Reset Timeout Period: Adjustable from 1ms to 640ms
• Operating Temperature Range: -40°C to +85°C
• Quiescent Current: 3µA (typical)

Pin Configuration

The MAX819MCPA+ has the following pin configuration:

1. VCC - Power supply input
2. GND - Ground reference
3. MR - Manual reset input
4. RESET - Reset output
5. TH - Threshold adjust input

Functional Features

• Voltage monitoring: The MAX819MCPA+ continuously monitors the input voltage and compares it with the user-adjustable threshold voltage.
• Reset function: When the monitored voltage falls below the threshold voltage, the device asserts the reset output, indicating a power-on reset condition.
• Manual reset: The manual reset input allows the user to manually assert the reset output, regardless of the monitored voltage level.
• Adjustable parameters: The threshold voltage and reset timeout period can be adjusted according to the specific requirements of the application.

Advantages and Disadvantages

Advantages

• High accuracy voltage monitoring
• Flexible threshold voltage adjustment
• Low power consumption
• Small package size for space-constrained applications
• Wide operating voltage range

Disadvantages

• Limited reset timeout period adjustment range
• Manual reset input may require additional external components for proper functionality

Working Principles

The MAX819MCPA+ operates by continuously comparing the input voltage with the user-adjustable threshold voltage. When the input voltage falls below the threshold voltage, the device asserts the reset output, indicating a power-on reset condition. The reset output remains asserted until the input voltage rises above the threshold voltage or a manual reset signal is received.

Detailed Application Field Plans

The MAX819MCPA+ finds applications in various electronic systems that require reliable voltage monitoring and reset functionality. Some potential application fields include:

1. Microcontrollers and microprocessors
2. Power management systems
3. Industrial control systems
4. Automotive electronics
5. Battery-powered devices

Detailed and Complete Alternative Models

1. MAX809MCPA+: Similar to MAX819MCPA+, but with fixed threshold voltage and reset timeout period.
2. MAX803MCPA+: Voltage monitoring and reset IC with adjustable threshold voltage and fixed reset timeout period.
3. MAX811MCPA+: Voltage monitoring and reset IC with fixed threshold voltage and adjustable reset timeout period.
