Power Management ICs (PMICs), also known as Supervisors, are specialized integrated circuits used in modern electronic systems to measure and manage voltage, current and heat. PMICs offer a variety of features and benefits, including improved power efficiency, reduced power consumption and improved safety. In this article we will discuss the application field and working principle of the S-80936CNMC-G86T2U PMIC.

Application Field

The S-80936CNMC-G86T2U is a high-performance, energy-efficient PMIC designed for use in battery-powered, mobile and Internet of Things (IoT) applications. It integrates advanced power management functions such as voltage regulation, current limiting, and thermal protection and can be used to power multiple devices. The wide input voltage range (2-5V) and robust outputs (3μA standby current) make it suitable for a wide range of power management applications.

The S-80936CNMC-G86T2U is widely used in a range of battery-powered applications including mobile phones, wearables, home appliances, health-care devices, and industrial equipment. It is also used in automotive and aerospace applications, which require high levels of performance and reliability.

Working Principle

The S-80936CNMC-G86T2U PMIC utilizes a ripple-mode switching regulator that provides a clean, low-noise power supply. The integrated power control components and an analog signal input provide precise control of the output voltage and current. In order to maintain efficiency and minimize power consumption, the power control components are disabled when the output current reduces by a predetermined amount.

The PMIC\'s integrated features also include a digital soft-start/shutdown feature that eliminates voltage spikes during startup and shutdown. This feature helps protect sensitive electronic components and reduces the risk of device damage. Additionally, the PMIC features a power-good signal, which allows the digital control logic to detect when the output voltage is out of range and shut down the device.

The S-80936CNMC-G86T2U PMIC also includes integrated thermal protection, which prevents the device from overheating. The PMIC utilizes an accurate voltage droop detection circuit that monitors the output voltage. When the voltage falls below a predetermined level, the circuit triggers a thermal mitigation sequence that reduces the load current and prevents the device from overheating.

In addition to its power control features, the S-80936CNMC-G86T2U PMIC offers a range of convenience features, such as a power-on-reset circuit, a power fail detect circuit, and a bulk voltage sense circuit. The power-on-reset circuit helps to ensure that the device\'s output voltage is within the specified range after power is applied, while the power fail detect circuit monitors the output voltage and sends a signal to the digital control logic to prevent over-voltage or under-voltage conditions.

Finally, the S-80936CNMC-G86T2U PMIC provides accurate output voltage control for improved system performance and extended battery life. The PMIC\'s advanced sense rectifier ensures accurate output voltage regulation, while its built-in voltage step-down circuit prevents over-current and over-temperature conditions. With its wide input voltage range, low quiescent current, and power fail detect circuit, the S-80936CNMC-G86T2U PMIC is an ideal solution for power management applications.
