Application Field: Automotive Voltage Regulation System

The ANUJ6426SV is a standby voltage generator specifically designed for automotive voltage regulation systems. With its wide input voltage range (4v to 14V) and low-dropout regulator, it can quickly respond and regulate to the wide variance of input. As it is designed for the automotive field, it is equipped with over-load, short circuit, over-voltage, over-temperature and under-voltage protection, ensuring its reliability in the vehicle environment, even with harsh driving conditions. These features also make it an ideal choice for applications that require low-noise and excellent line and load regulation.

Working Principle

The ANUJ6426SV is a DC-DC switching regulator which uses the PWM technique to generate a steady voltage output. It is based on a Error Amplifier, an internal PWM Generator, an External MOSFET and an Internal Comparator Circuit. The Error Amplifier compares the feedback voltage on the output pins to the reference voltage on the reference input pins (Vref pin). When there is a difference between the two voltages an error current is generated that controls the PWM generator. The PWM into their control signal is also used to drive the external MOSFET, which then modulates the energy stored in the output inductor. The internal Comparator Circuit monitors the voltage across the output inductor and will disable the output if the voltage exceeds a certain limit. When the output is disabled, the output voltage is maintained steady by the resistor divider.

In summary, the ANUJ6426SV is a high-performance standby voltage generator designed specifically for automotive voltage regulation systems. With its wide input voltage range and low-dropout regulator, it is capable of delivering fast transient response and excellent line and load regulation. Additionally, it offers over-load, short circuit, over-voltage, over-temperature and under-voltage protection, making it a highly reliable choice in various driving conditions.
