The IR2131JTR is an integrated circuit (IC) component developed by Infineon Technologies. It is a high-performance three-phase brushless DC motor controller that is specifically designed for driving power MOSFETs in various motor control applications, including industrial, automotive, and consumer electronics.
One of the key features of the IR2131JTR is its versatile motor control capability. It enables the control of both sensor-based (Hall effect or encoder) and sensorless (back-EMF sensing) brushless DC motors. This flexibility allows the IC to be used in a wide range of motor control systems, providing designers with more options for their applications.
The IC supports a wide input voltage range, ranging from 8V to 28V. This feature ensures compatibility with different power supply setups, making it suitable for a variety of motor control designs. Additionally, the IR2131JTR incorporates built-in protection features such as undervoltage lockout, overvoltage protection, and overcurrent protection, which help safeguard the circuit and the connected motor against potential damage.
The IR2131JTR offers six independent high- and low-side gate drivers, each capable of driving MOSFETs or IGBTs with high peak current and sourcing/sinking capability. This allows efficient motor control by providing reliable and fast switching performance.
Another noteworthy feature of the IC is its advanced dead-time control capability
