Introduction to PMIC - Supervisors

Power management integrated circuits (PMICs) are special-purpose integrated circuits used for managing power in different systems. They are responsible for providing adequate power to all the components of a system at its different operational states, and for allowing the system to enter sleep or idle modes in order to save energy. Supervisors are a type of PMICs which provide the control, status monitoring and fault protection circuitry for the system.

S-80936CLPF-G66TFG Overview

The S-80936CLPF-G66TFG is a microprocessor supervisory circuit (also known as μP supervisor) designed to monitor power supplies in microprocessor-based systems. It offers a low threshold voltage, 3.2V, compared to the industry standard of 4.63V. This helps to extend system battery life and reduce system cost. The built-in low battery reset functionality provides excellent system reliability and eliminates the need for a separate reset IC and power failure reset circuit. The device also has a serial 4-wire interface that allows the user to set the device’s various parameters.

S-80936CLPF-G66TFG Application Fields and Working Principle

The S-80936CLPF-G66TFG is typically used as a supervisor in microprocessor-based systems to monitor voltage levels, current levels and power supply status. It includes a detection circuit to detect over and undervoltage conditions, a current detection circuit to detect whether the system is in an operating or suspended state, and a reset output circuit to reset the system under low battery voltage or overvoltage situations.When a system is powered on, the S-80936CLPF-G66TFG will check the power supply voltage by comparing a reference voltage to the voltage it senses. If the voltage is below the threshold, the device will issue a reset signal to the system. The device will also monitor the current being supplied, and if the current consumption exceeds a certain threshold, it will again issue a reset signal. Finally, it can also check the wake-up voltage, and if the wake-up voltage is lower than a preset threshold, it will trigger a reset.The S-80936CLPF-G66TFG is suitable for a variety of applications, including laptops, cell phones, digital television (DTV) products, and consumer and industrial products. The device can also be used in automotive, medical and security applications.

Advantages of the S-80936CLPF-G66TFG

The S-80936CLPF-G66TFG has several advantages over other PMIC supervisors. First, its low threshold voltage reduces battery energy usage, helping to prolong battery life. Second, its built-in reset circuitry eliminates the need for a separate reset IC and power failure reset circuit, thus reducing design complexity and cost. Finally, its serial 4-wire interface allows the user to set the device’s various parameters such as the reset time delay, reset threshold, and wake-up thresholds.

Conclusion

The S-80936CLPF-G66TFG is a PMIC supervisor that provides good protection against overvoltage and undervoltage conditions, in addition to monitoring current levels and system power supply status. Its low threshold voltage helps to reduce system cost and extend system battery life. The device also features a convenient serial 4-wire interface that allows the user to configure the device’s various parameters.
