  3. MR: Manual reset input
  4. RESET#: Active-low reset output
  5. TH: Threshold voltage selection pin
  6. CT: Capacitor connection for reset timeout adjustment

Functional Features

  • Monitors the supply voltage and asserts a reset signal when it falls below the threshold voltage.
  • Provides an active-low reset output that remains asserted until the supply voltage rises above the threshold voltage.
  • Offers adjustable reset timeout period through an external capacitor connected to the CT pin.
  • Allows manual reset by asserting a low level on the MR pin.

Advantages and Disadvantages

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

Disadvantages: - Limited threshold voltage options - Fixed power-on reset delay

Working Principles

The MAX6457UKD0A+TG075 is designed to monitor the supply voltage of electronic systems. It compares the supply voltage with a user-defined threshold voltage. When the supply voltage falls below the threshold voltage, the IC asserts an active-low reset signal. The reset signal remains asserted until the supply voltage rises above the threshold voltage. The reset timeout period can be adjusted using an external capacitor connected to the CT pin. Additionally, a manual reset option is available by asserting a low level on the MR pin.

Detailed Application Field Plans

The MAX6457UKD0A+TG075 is commonly used in various applications, including:

  1. Battery-powered devices: Ensures proper operation and prevents damage due to low battery voltage.
  2. Microcontrollers: Provides reliable reset functionality during power-up and brownout conditions.
  3. Industrial control systems: Monitors supply voltage to prevent malfunctioning or data corruption.
  4. Automotive electronics: Protects sensitive components from voltage fluctuations and ensures safe operation.
  5. Home automation systems: Enables graceful shutdown and recovery during power outages.
