Power Management Integrated Circuits (PMICs) are responsible for providing the design engineer with the means to control, monitor and protect the systems aboard an electronic device. One such device is the ADM709MANZ Supervisory. The ADM709MANZ is a dual high-precision micro-processor supervisor from Analog Devices (AD) which acts like a gatekeeper for the system. It allows the device to monitor and control the power supply’s load and regulate the voltage and current being provided to the microprocessors, memory chips, and other components in the system.

The ADM709MANZ features industry-standard 14pin PDIP (plastic dual in-line package) configuration, making it compatible with numerous industry applications. With an operating range of –20°C to +125°C, this device is suitable for a variety of challenging conditions and environments. and is rated for an operating voltage of 2.5V to 5.5V.

The ADM709MANZ is designed as a system reset generator and features an active-low open-drain Reset output with an adjustable threshold voltage and a time-delay reset. The onboard reset voltage is pre-set to trigger at 3.45V±1% and a manual reset can occur via the MR pin. The ADM709MANZ also includes a watchdog timer, allowing for regular checking of the systems’ condition, ensuring that the system is securely powered and operating correctly under any given conditions.

The ADM709MANz Supervisory is fully programmable via the onboard pins and registers, allowing for the adjustment of the reset delay time, power-up/down-delay times, reset assertion widths, and more. With an active LOW reset signal, the device ensures that the system remains stable and power efficient.

The combination of the components and features of the ADM709MANZ allows for the design engineer to have complete control over the supervisory performance of the device. It is tailored to have low-power requirements and long-term stable behavior. This make it extremely suitable for configurable Industrial, Automotive, Home Appliances and Lighting applications, where the system must remain stable and efficient at all times.

Due to its small size, low-power requirements, high accuracy, and adjustable features, the ADM709MANZ is ideal for industrial and embedded applications. Its integrated watch-dog timer, reset generator, and adjustable timer thresholds provides for reliable control over the power supply and system reset operations, making it an easy-to-use solution for designers looking for on-demand system supervision.
