The BR2C12AC is an industrial-grade, high-performance, full-bridge motor-control integrated circuit (IC). It has unique features, such as low on-resistance, internal precharging and active dead-time control, which make it suitable for a wide range of applications. This article will provide an overview of the BR2C12AC application field and its working principle.

Applications

The BR2C12AC is mainly used for high-voltage motor control, such as in power tools, 3-phase motor drives and adjustable speed drives (ASDs). It is widely used in a variety of aspects such as electric vehicles, household appliances, office automation systems, automation equipment and industrial process control.

Working Principle

The BR2C12AC is an integrated circuit (IC) consisting of two half-bridges for controlling motors. Each half-bridge contains four MOSFETs (metal oxide semiconductor field-effect transistors) to control voltage across the motor. The circuit also has two precharge transistors that precharge the capacitors connected to the MOSFETs prior to switching, which helps reduce EMI/RFI (electromagnetic interference/radio frequency interference).

The circuit also includes an internal dead-time controller, which limits the amount of current that flows through the motor at any instant. This protects the motor from over-current as well as preventing shoot-through current. In addition, the IC features an over-current channel detection circuit, which can detect the presence of a short-circuit in the system and shut down the system if needed.

The BR2C12AC has a wide input voltage range, from 6V to 80V, making it suitable for a variety of voltages and applications. In addition, it has a wide temperature range, from -40°C to 125°C, making it suitable for applications operating in extreme temperatures. Finally, it has a high surge current capability of up to 500A.

Conclusion

The BR2C12AC is a high-performance, full-bridge motor control IC suitable for a wide range of applications. It features a low on-resistance, internal precharging and active dead-time control, making it reliable and able to handle various conditions. Its wide input voltage and temperature ranges as well as its surge current capability make it suitable for a variety of applications from electric vehicles to industrial process control.
