P9024AC-0AWGI is a specialized power management integrated circuit (PMIC) designed to serve the consumer and automotive markets. It is an optimized single IC solution for general-purpose, high-side load switch applications, simplifying the power-supply solution from the automotive level. The IC provides a high current carrying capacity of 20A continuous, and includes a range of customizable safety features and integrated programmable limit protections.

What is P9024AC-0AWGI

P9024AC-0AWGI is a 20A, single-channel integrated circuit (IC) solution for automotive, ATV, and industrial load switch applications. It has a range of advantages, including improved efficiency and protection, safety features, automated diagnostics, and a 94%-96% peak efficiency at 12V. By reducing the bill of materials (BOM) and maintenance costs, this IC solution optimizes the power-supply solution from the automotive level without compromising on performance, durability and reliability.

Application Fields

The P9024AC-0AWGI is suitable for a range of management and switching applications, such as lighting systems, electric windows and window lifts, air conditioning, and electronic power steering in automotive applications, or aircraft and industrial machines in the industrial application field.

In addition to automotive and industrial applications, this IC is also suitable for applications such as gaming equipment, LED displays and LED control, off-grid renewable energy, household appliances, and ATV applications.

Active Low Side Driving

The P9024AC-0AWGI IC is optimized for output voltage flexibility, high peak efficiency and active low-side driving (SSPC). This solution is different from traditional PMIC solutions in that it helps reduce the bill of materials (BOM) by providing a single IC solution for the power supply system. The IC also features heavily integrated protection features, such as over-temperature protection (OTP), over-voltage protection (OVP), and over-current protection (OCP).

This integrated IC operates with a single low-side switch and delivers a low quiescent current, high efficiency, and integrated protection features. P9024AC-0AWGI helps reduce the BOM and make power management more efficient and reliable.

Working Principle

P9024AC-0AWGI utilizes active low-side driving (SSPC) for its load switch applications instead of the traditional PMIC solutions. The regulator includes a voltage regulator, a PWM modulator, and a coil current limiter. The PWM modulator is used to modulate the current applied to the load to regulate its voltage. The coil current limiter ensures that the current drawn from the supply does not exceed the maximum allowed amount. The voltage regulator regulates the output voltage of the load, and the over-current protection (OCP) trips to protect from over-voltage, over-temperature, and under-voltage conditions.

In addition, the IC also has an integrated EEPROM function, which can be programmed to provide a range of user thresholds and features. This allows customization of the IC\'s behavior to suit required applications, such as providing temperature compensation, current sharing, and power-on/off sequencing.

Conclusion

The P9024AC-0AWGI is a specialized power management integrated circuit (PMIC) suitable for a range of switching and management applications. With its active low-side driving (SSPC) and integrated protection features, it helps reduce bill of materials (BOM) and increase efficiency and reliability. This makes it an excellent choice for automotive, ATV, and industrial applications.
