Today, automotive electronic systems face a variety of changing requirements and high performance demands. As a result, selecting an appropriate power management integrated circuit (PMIC) that meets application needs becomes increasingly important, and the 96FAN-775P2U3.4-CJ PMIC provides intelligent power control solutions for automotive application fields. This article will introduce the application field and working principle of this device.

The 96FAN-775P2U3.4-CJ is a versatile PMIC designed for automotive power management applications, with intelligent features such as current protection, overvoltage protection, direct load control, load sharing and active device shutdown for safe and efficient power supply. Its wide range of integrated features and on-chip protections save valuable system space and reduce power consumption. Automotive applications of the 96FAN-775P2U3.4-CJ PMIC include engine control systems, air conditioning systems, transmission control systems, powertrain control systems, EV/HEV powertrain systems, body control systems, gateways, and other vehicle control systems.

The 96FAN-775P2U3.4-CJ PMIC features an integrated boost regulator and adjustable buck converter that supports a wide range of output voltage levels. The adjustable buck converter output voltage range is from 0.5 V to 12V, and the integrated boost regulator directly supplies multiple power rails from a 12V input. The additional 7 AMS1117 low dropout (LDO) regulators provide output current capability up to 1.5A. The multiple power rails of the 96FAN-775P2U3.4-CJ enable efficient load sharing and power management for automotive applications.

Moreover, the 96FAN-775P2U3.4-CJ PMIC supports active current protection and overvoltage protection. The integrated current protection switches off the output voltage automatically when the output current reaches the overcurrent limit level, while the integrated overvoltage protection senses and switches off the output voltage when the voltage exceeds the upper limit level. This allows the system to monitor and react quickly to any overcurrent and overvoltage conditions.

In addition, the 96FAN-775P2U3.4-CJ PMIC provides an additional output enable pin to control the output voltage shutdown state. The Output Enable pin allows a system to shut down the power rail or just partially reduce the load current. When the output is disabled, the power supply will enter into the power down state. This feature is beneficial for applications that have tight power requirements.

Moreover, the 96FAN-775P2U3.4-CJ provides a load sharing feature that enables multiple power rails to be connected in parallel and share the load current. This feature not only saves system space but also allows the system to evenly split and distribute the load current among multiple power rails. It ensures that all the power rails in the system have the same voltage levels and that the combined load current does not exceed the specified current levels for each of the power rails.

Lastly, the 96FAN-775P2U3.4-CJ PMIC has a com-mode power control feature that allows the system to control the output voltage without requiring additional components. This feature reduces both system cost and power consumption. The com-mode power control feature enables distributed output voltage control to increase system efficiency. Com-mode power control is also beneficial for systems with multiple power sources.

In summary, the 96FAN-775P2U3.4-CJ PMIC provides a highly integrated USB power solution for various automotive applications. Its advanced built-in features, such as current protection, overvoltage protection, direct load control, load sharing and active device shutdown, offer superior performance and safety for reliable power management. Its multiple output voltage levels, load sharing features, and com-mode power control capabilities reduce system cost and maximize system efficiency for automotive applications.
