Integrated circuits are becoming a standard component of most modern electrical systems and devices. They can provide various functions to a system, from power supply regulation and protection to communication with other devices and subsystems. The S-80855CNMC-B9GT2G is an example of a PMIC (Power Management Integrated Circuit) product specifically designed to monitor and protect against overvoltage, undervoltage and brownouts in systems, making it an important component for quality design and reliable operation. This document will discuss the S-80855CNMC-B9GT2G\'s application field, its working principle and other attributes.

Application Field

The S-80855CNMC-B9GT2G can be used in a wide range of systems, including automotive and industrial designs. It is designed to protect and monitor systems using up to 36 V of regulated power and can detect overvoltage, undervoltage and brownouts in this voltage range, as well as any associated overcurrent or over-temperature conditions. It also provides fault diagnosis capability and can be used to protect and monitor battery powered systems or systems with limited or no regulation.

The S-80855CNMC-B9GT2G has been designed with automotive safety and reliability in mind, making it suitable for use in battery, powertrain and safety related systems. It is fully compliant with the relevant automotive safety and EMC standards, making it an attractive choice for designs that require a high degree of protection and reliability. Along with its automotive focus, the S-80855CNMC-B9GT2G is also suitable for industrial, telecommunication, and power modulator applications.

Working Principle

The S-80855CNMC-B9GT2G works by using a pulse width modulator (PWM) to monitor and regulate voltages and currents. The integrated circuit (IC) adjusts the duty cycle of the PWM signal according to the sensed voltage, current and temperature inputs, enabling precise control over the system\'s power levels. The S-80855CNMC-B9GT2G has two main outputs, a main output and an auxiliary output. The main output provides the precise regulated voltage and current, while the auxiliary output can be used to drive external devices, such as fans or other load devices.

The S-80855CNMC-B9GT2G is also equipped with several protection circuits, which can detect overvoltage, undervoltage, brownouts, and over-temperature conditions. When any of these conditions are detected, the S-80855CNMC-B9GT2G will activate the on-chip thermal shutdown circuit, forcing the system to shut down and protecting it from further damage. This protective circuit can also be triggered manually by means of an external pin or interface.

Other Attributes

The S-80855CNMC-B9GT2G is designed to provide excellent temperature, current, and voltage protection while operating at a very low quiescent current. The IC is also designed to reduce switching losses and reduce EMI noise, making it an ideal solution for noise-sensitive applications. The integrated circuit is RoHS-compliant and has a small form factor, making it ideal for space-constrained designs.

The S-80855CNMC-B9GT2G is an important component for a variety of applications and designs, providing robust voltage and current protection and monitoring. Its wide application field, low power consumption, EMI noise reduction, and small form factor make it an attractive solution for automotive, industrial, and telecommunication designs.
