PMIC - Supervisors provide advanced system reset functionality, which can help to recover from a wide variety of in-system fault conditions. The S-80960CNMC-G9WT2G is an excellent example of this type of supervisor. In this article, we’ll take a deep dive into the S-80960CNMC-G9WT2G, exploring its application field and working principle.

Application Field

The S-80960CNMC-G9WT2G is designed to monitor the power supply of advanced consumer, industrial and automotive applications, including servers, set-top boxes, networking equipment, automotive infotainment systems and industrial computers. It provides a reliable reset mechanism that is optimized for fault detection, minimizes false resets and is effective in systems with transients up to 8 V. This part is architecture independent and can operate with a wide variety of voltage levels, providing flexibility to reduce the inventory list.

The S-80960CNMC-G9WT2G is RoHS compliant, meaning it is free from hazardous materials and helps manufacturers adhere to the EU’s Restrictions of Hazardous Substances (RoHS) directive. It requires just 1.6 µA operating current at Vdd 3.3 V and is available in an industry standard 8-pin SOP package. It is also fully compliant with the JEDEC standard.

Working Principle

The S-80960CNMC-G9WT2G has two primary functions: monitoring the system power supply and generating a reset signal if the power supply fails. The low and high input reference voltage thresholds are factory pre-set, allowing for an easy one-time set-up procedure. The high voltage is set to 1.05 V above the positive power supply rail and the low voltage is set to 0.90V.

When the power supply voltage falls below the factory set low voltage threshold of 0.90V, the S-80960CNMC-G9WT2G generates an active low reset signal and keeps it active until the power supply voltage exceeds the factory-set high voltage threshold of 1.05V. This ensures a stable operation of the system by resetting the microcontroller in case of a fault. The reset signal is automatically generated, removing the need for separate circuit components.

The S-80960CNMC-G9WT2G also has an open drain input RESETIN pin, which allows the reset signal to be driven externally. This can be used to reset the system in case of an emergency shutdown or in case of a watchdog timeout. It also allows for easy integration into existing system designs.

In addition to generating a reset signal, the S-80960CNMC-G9WT2G also features logic control pins that can be used for further features. The PWDN pin is used to disable the monitoring of the power supply, and the WRT pin can be used to control the reset output signal.

The S-80960CNMC-G9WT2G also features an active reset delay pin (RESET_DLY) that can be used to delay the active reset signal. This improves the response time of the reset signal and helps to protect against sudden voltage drops. It can also be used as an interrupt that can delay the reset signal in case of a fault detection.

Overall, the S-80960CNMC-G9WT2G is a sophisticated piece of power management hardware that offers a range of features designed to help designers keep their systems running smoothly. Its wide application field, easy integration and advanced reset functions make it an ideal choice for many power monitoring and protection applications.
