Power Management Integrated Circuits (PMICs) are widely used in the automotive industry and are essential for reliable and efficient operation of electronic systems. The most commonly used PMICs are Maxim Integrated\'s MAX16969DGEE/V+T. This article will discuss the application field and working principle of the MAX16969DGEE/V+T.

Applications

The MAX16969DGEE/V+T is a dual-channel 6V buck regulator integrated circuit that is designed for automotive ECU applications. The device integrates two channels of high current step-down DC/DC converters and an integrated power switch for each channel. The two DC/DC converters operate from a 6V input and can output voltages from 0.8V to 5V. Each channel can support an output current of up to 6A. The MAX16969DGEE/V+T is specifically designed for automotive ECUs, and can be used to power a variety of automotive applications such as engine control, ABS, climate control, and infotainment systems.

The device is AEC-Q100 qualified and is available in a space-saving 8-pin HVSSOP package. This makes the MAX16969DGEE/V+T an ideal solution for automotive ECUs where size and weight are critical.

Working Principle

The MAX16969DGEE/V+T is a dual-channel 6V buck regulator integrated circuit. The device consists of two independent step-down converter channels, each operating from a 6V input and capable of delivering up to 6A at the output. The output voltage of the DC/DC converters is adjustable from 0.8V to 5V.

Each channel consists of two stages: a high-side power switch, and a PWM controlled buck converter circuit. The high-side power switch is responsible for controlling the amount of current flowing through the buck converter. The PWM controlled buck converter then takes the input voltage, reduces it to the desired output voltage and regulates the output current. The device also includes an integrated over-current protection circuit to protect against excessive output current.

The MAX16969DGEE/V+T is designed for automotive use and is AEC-Q100 qualified. This ensures that the device is reliable, robust and suitable for harsh automotive environments. The device is available in a space-saving 8-pin HVSSOP package, making the MAX16969DGEE/V+T an ideal solution for automotive ECUs where size and weight are critical.

Conclusion

The MAX16969DGEE/V+T is a dual-channel 6V buck regulator integrated circuit that is designed for automotive ECU applications. The device integrates two channels of high current step-down DC/DC converters and an integrated power switch for each channel. It is AEC-Q100 qualified and is available in a space-saving 8-pin HVSSOP package, making the MAX16969DGEE/V+T an ideal solution for automotive ECUs where size and weight are critical. The device is suitable for a variety of automotive applications such as engine control, ABS, climate control, and infotainment systems.
