• Package: SOT-23-5
• Essence: This product is a voltage supervisor IC that monitors the power supply voltage of a system and provides a reset signal when the voltage falls below a certain threshold.
• Packaging/Quantity: Tape & Reel (3000 pieces per reel)

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Threshold Voltage Options: 2.5V
• Reset Timeout Period: Adjustable from 1ms to 640ms
• Quiescent Current: 3µA (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX16057ATT25+T has a total of 5 pins:

1. GND: Ground connection
2. RESET: Active-low reset output
3. MR: Manual reset input
4. VCC: Positive power supply input
5. TH: Threshold voltage selection pin

Functional Features

• Voltage Monitoring: The MAX16057ATT25+T continuously monitors the power supply voltage and asserts the reset signal when it drops below the threshold voltage.
• Precision: The device offers accurate voltage monitoring with a low threshold voltage option of 2.5V.
• Reset Timer: The reset signal remains asserted for a programmable timeout period, allowing the system to reset properly.
• Manual Reset: The MR pin allows for manual reset control, overriding the automatic reset functionality.

Advantages and Disadvantages

Advantages: - Low power consumption - Precise voltage monitoring - Adjustable reset timeout period - Manual reset capability

Disadvantages: - Limited threshold voltage options - Single package option (SOT-23-5)

Working Principles

The MAX16057ATT25+T operates by comparing the power supply voltage with the threshold voltage set by the TH pin. When the voltage drops below the threshold, the reset output is asserted. The reset signal remains active for a duration determined by the reset timeout period. The MR pin allows for manual reset control, providing flexibility in system reset management.

Detailed Application Field Plans

The MAX16057ATT25+T finds applications in various fields, including: 1. Battery-Powered Devices: Ensuring proper system reset and power management in portable electronics. 2. Industrial Control Systems: Monitoring power supply voltage to prevent malfunctions and ensure reliable operation. 3. Automotive Electronics: Providing voltage supervision for critical systems, such as engine control units and safety modules. 4. Home Automation: Enabling safe and reliable operation of smart home devices by monitoring power supply integrity.
