Power management integrated circuits (PMICs) are rapidly becoming an essential component of all modern electronic designs, especially in the embedded and mobile market. From mobile phones to TVs and home appliances to battery powered medical devices, PMICs are used everywhere. Supervisors are a type of PMIC designed to protect electronic devices from unpredictable and potentially damaging conditions such as surge and overvoltage protection.

The AZ809ANSTR-G1 is a new PMIC supervisor from Diodes Incorporated that combines a voltage detector, overvoltage protection, reset source, and watchdog timer in a single 5-lead package. With its miniature 5-lead SOT-23 package, the AZ809ANSTR-G1 provides a compact and cost-effective solution for monitoring and managing power conditions in power-sensitive applications.

Application Field:

The AZ809ANSTR-G1 can be used in a wide variety of applications where power monitoring and management are essential. It is especially suitable for use in embedded applications such as handheld devices, automotive electronics, portable instruments and medical devices. Features such as over-voltage protection, low leakage current, fast response time and adjustable output delay make the AZ809ANSTR-G1 an ideal choice for use in cost-sensitive applications.

Working Principle:

The AZ809ANSTR-G1 works by monitoring an input voltage and triggering a reset signal based on a user-programmable threshold. The device is equipped with a dual-stage reset source, with each stage having its own programmable threshold. This allows the device to be used in applications where a wide range of reset points is required. The device also features a watchdog timer to detect whether the host CPU has malfunctioned and initiate a reset if appropriate.

When the input voltage is within the detection range, the device\'s internal circuitry constantly monitors the voltage level. If the voltage rises above the user-set threshold, a reset signal is issued. The reset signal is only active for the duration of the overvoltage condition, and then the device will continue to monitor the voltage levels. If a voltage drop is detected below the user-set level for a defined period of time (adjustable), an active-low reset is generated, indicating that a normal operating range is present.

The AZ809ANSTR-G1 also features an adjustable watchdog timer. This timer can be set to issue a reset signal when the monitored voltage level is outside of the specified range for a set amount of time. This provides additional protection against unexpected system failures, making the device an essential component of any power management system.

In summary, the AZ809ANSTR-G1 is a highly reliable and cost-effective power management supervisor. It is suitable for use in a wide variety of embedded and automotive applications, and provides robust protection against overvoltage and system failure. It is an essential component of any power system, providing the necessary protection and reliability to ensure that systems remain functioning at peak performance.
