常見問題解答

What is ADM803SAKSZ?

The ADM803SAKSZ is a voltage monitoring integrated circuit (IC) manufactured by Analog Devices. It is specifically designed as a microprocessor supervisory circuit to monitor power supply voltages and provide a reset signal to the microcontroller or processor when the voltage falls below a predefined threshold.

How Does ADM803SAKSZ Work?

The ADM803SAKSZ operates by continuously monitoring the input voltage from the power supply. When the voltage drops below a specified level, the device triggers a reset signal to ensure the proper functioning of the microcontroller or processor. This helps prevent erratic operation or software glitches due to a low supply voltage, thereby enhancing system reliability.

How Many Pins does ADM803SAKSZ have and What are the Functions of the Pinout Configuration?

The ADM803SAKSZ comes in a 5-lead SC70 package. The pinout configuration includes:

  • VDD: Power supply input pin.
  • RESET: Reset output pin to the microcontroller.
  • MR: Manual reset input pin for external reset control.
  • GND: Ground pin.
  • NRST: Not Reset output pin for external monitoring.

What are the Pros and Cons of ADM803SAKSZ?

Pros:

  • Reliable Reset Function: Ensures safe reset operation upon power supply voltage fluctuations.
  • Low Power Consumption: Operates with very low current consumption, suitable for battery-powered systems.
  • Compact Size: The small SC70 package saves PCB space and is suitable for compact designs.
  • Wide Voltage Range: Supports monitoring of a wide range of supply voltages for versatility.

Cons:

  • Single Power Supply Monitoring: May not be suitable for applications requiring monitoring of multiple power supplies.
  • No Adjustable Threshold: The reset threshold is fixed and cannot be adjusted in the ADM803SAKSZ.

Are There Any Equivalents/Alternatives to ADM803SAKSZ for Recommendation?

  • Alternatives to the ADM803SAKSZ include the MAX809 from Maxim Integrated and the TC54 from Microchip Technology.
  • The DS1233 from Maxim Integrated is also a comparable voltage monitoring IC with similar features.
