The ADM1232 from Analog Devices Inc. is a state-of-the-art microprocessor supervisory circuit that ensures reliable operation of microprocessor (µP) systems. This compact yet powerful component monitors the power supply voltage to protect against damage caused by out-of-tolerance power levels. Its primary function is to safeguard your µP systems by providing a reset signal to the processor upon detecting voltages that fall below a predetermined threshold, ensuring the system restarts in a known, stable state after a power failure.

Key Features:

  • Precision Monitoring: The ADM1232 offers precise monitoring of the power supply voltage, with a factory-trimmed threshold that guarantees accurate detection of under-voltage conditions.
  • Automatic Reset Generation: Upon detection of an out-of-tolerance condition, the device automatically generates a reset signal for a minimum of 140 ms after VCC has risen above the reset threshold, ensuring proper system reboot.
  • Manual Reset Input: A manual reset input is provided, allowing the system to be reset externally with a pushbutton or other input signal, enhancing system control and user intervention capabilities.
  • Low Power Consumption: Designed for energy efficiency, the ADM1232 features a low supply current, making it an ideal choice for portable and power-sensitive applications.
  • Wide Operating Voltage Range: The device supports a broad operating voltage range, accommodating various µP and logic systems, which increases its versatility across different platforms.


The ADM1232 is suitable for a diverse range of applications where reliable system operation is critical. These include:

  • Computers and Servers
  • Embedded Systems
  • Portable/Battery-Powered Equipment
  • Industrial Controllers
  • Telecommunications Equipment

In summary, the ADM1232 is a robust, reliable solution for µP system supervision, offering features that ensure system integrity and stability. Analog Devices Inc. has engineered this component to meet the stringent demands of modern electronic systems, providing designers with a trusted tool for enhancing system performance and protection.
