A BD9306AFVM-TR (hereafter referred to as BD9306) is a two-channel non-synchronous buck switching controller specifically developed for automotive DC-DC systems. This chip is a part of Voltage Regulators, specially of the DC DC Switching Controllers type, and it can be used in several applications and has a well-defined working principle.

Application Field of BD9306AFVM-TR

BD9306 can be used in various applications, such as:

• Car Accessory Power Supply
• Reverse Polarity Theft Deterrence
• Low Input Voltage Supplies
• Power- supply Monitoring
• Motor Control and Automation
• Other Automotive Applications

It can also be used in contexts where a low profile solution is needed, since it offers compact sizes (3.3mm x 3.3mm) and an internally generated 1.4V to 2.4V supply for driver transistors.

Working Principle

BD9306 works as a non-synchronous buck switching controller, which means it uses two switch elements (a high-side MOSFET and a low-side MOSFET) to control currents in the power supply chain. It has a low-power operating mode and an internal gate driver to control those MOSFETs.

In its operating principle, the device is designed to monitor the voltage of the power supply chain, detecting the switching actions and making sure these actions are performed with the correct voltages and timings, so the output voltage is correct and constant. It also provides protection against fault current and overvoltage conditions.

BD9306 has internal overhead feature: it senses the temperature of the system and takes action when operating temperature rise beyond its limits, so it provides temperature protection.

Conclusion

BD9306AFVM-TR is a two-channel non-synchronous buck switching controller developed for automotive DC-DC systems. It belongs to Voltage Regulators’ DC DC Switching Controllers type, and provides efficient and accurate power supply control. It can be used in many applications and its working principle ensures constant and safe output voltage.
