Power Management Integrated Circuits (PMICs) play an essential role for a wide variety of applications, including driving motors and controlling power-consuming components like LCDs, LEDs and radio receivers. PMICs are used to regulate, manage and monitor system hardware, including but not limited to clock sources, linear and switching power converters, and input battery. Supervisors are one of the main types of PMICs, having the ability to monitor a power supply voltage and can reset the system when the voltage exceeds a predetermined threshold. The S-80952CLNB-G7NT2G is an example of a supervisor with features and specifications that make it suitable for a variety of applications.

Overview of S-80952CLNB-G7NT2G

The S-80952CLNB-G7NT2G is a low power, single channel supervisor that provides excellent voltage monitoring capability. It has an operating voltage range from 2.55V to 5.5V, and it is capable of monitoring multiple power sources ranging from 1.5V to 5.5V for accurate voltage monitoring of over- and under-voltage conditions. The S-80952CLNB-G7NT2G also features an integrated adjustable watchdog timer which resets the system in the event of excessive device timeout. Furthermore, the S-80952CLNB-G7NT2G also has an active low reset that can be used to manually reset the system. Low power consumption and low current requirements make the S-80952CLNB-G7NT2G ideal for applications with tight power budgets.

Application Fields

The S-80952CLNB-G7NT2G is well-suited for portable consumer electronics applications including PDAs, digital cameras, and other hand-held devices. With its low power consumption and low current requirements, the supervisor is ideal for mobile and battery-operated applications where power consumption and component count are paramount. Other potential applications include single board computers, embedded system hardware, and automotive electronics.

Working Principle

The working principle of the S-80952CLNB-G7NT2G is to constantly monitor a selected power supply voltage such as one from a battery or from an external power source. If the voltage level drops or increases beyond a predetermined threshold, then the supervisor will generate a reset pulse and reset the device. The supervisor is also capable of monitoring multiple input power sources, so each individual source can be monitored for over- and under-voltage conditions. Additionally, the watchdog timer can be used to reset the system if a long period of inactivity has occurred.

Conclusion

The S-80952CLNB-G7NT2G is an example of a Supervisor PMIC, which is well-suited for a wide variety of applications. The supervisor can monitor multiple power sources, provide active low reset functionality, and it has a low power consumption and current requirement. It has potential applications in battery-operated, handheld electronics, single board computers, embedded systems, and automotive electronics. A key feature of the S-80952CLNB-G7NT2G is the ability to accurately monitor power supplies for over- and under-voltage conditions.
