A PMIC - Supervisors, the SP708SCN-L, is a voltage supervisor designed to provide high accuracy detection of fixed voltage thresholds with a push-pull output and low Power consumption.It is used in multiple applications including 5V or below external power supply, 5V or below internal power supply, power supply voltage monitoring, reset control and watchdog reset, reset of other circuit blocks, and system reset. The SP708SCN-L provides superior protection and monitoring for system power rails with enhanced reliability, accuracy, and simplicity.

In terms of its application field, the SP708SCN-L can be applied in various areas of electronics. including consumer electronic and information technology. It can be used to monitor the status of the power on system reset, determining the correct operation of digital and analog systems and automated test systems. In addition, it is suitable for output control and digital logic reset control as well as microcontroller (MCU) reset control. Moreover, the SP708SCN-L is also applicable to personal computer industrial control systems and web applications.

As the working principle of the SP708SCN-L is concerned, the voltage supervisor is divided into two parts: the voltage reference (VREF) and comparator. The VREF is a constant voltage signal of the same magnitude as the voltage under monitoring. It is provided by either an on-chip band gap circuit or an external reference source such as a precision voltage divider. The comparator is a circuit that continuously monitors the voltages of the monitored signal and the voltage reference. Whenever the monitored voltage drops below the reference voltage, the comparator generates a voltage transition at its output.

In addition, the SP708SCN-L has an adjustable pre-set threshold level. This allows system designers to have the flexibility to select a voltage level that best suits their need for the most reliable operation. An adjustable leveling slope also allows engineers to select the transition level of a signal. This is especially useful in automotive applications as it ensures proper signal level is detected by the device even during transition periods.

The SP708SCN-L is designed to provide superior performance in terms of accuracy, power efficiency, and reliability. It features push-pull output, low operating current, low operating voltage and fast response time. These features make it ideal for high power and sensitive applications where accuracy and reliability of low-power systems are of great importance. Moreover, it provides precision reference status monitoring with low power consumption, which reduces the system power budget and improves power efficiency. It can also reduce the component count by integrating the monitoring task and reset control in the same IC.

To summarize, the SP708SCN-L is an ideal voltage supervisor for a variety of applications, ranging from consumer electronics and information technology to industrial control systems and web applications. It can be used to monitor the status of power on system reset, to determine the correct operation of digital and analog systems and automated test systems, as well as to provide output control and digital logic reset control. It is designed to provide high accuracy detection of fixed voltage thresholds with a push-pull output and low power consumption. These features make the SP708SCN-L the ideal voltage supervisor for various applications.
