TriC3? 4.5 V to 60 V, Three-phase Brushless DC Motor Gate Driver
BD67871MWV-Z is mounted an Innovative Active Gate Drive (TriC3?) which suppresses EMI and reduces heat generation of MOSFET power devices in motor drive systems. TriC3? achieves these functions by monitoring various voltages around the MOSFET power device and using this voltages information to intelligently control the gate drive current of the MOSFET power device. It is a gate driver IC designed for three-phase brushless DC motor applications. It can drive three half-bridges consisting of six N-Channel power MOSFETs up to 60 V. It has synchronous rectification function during bootstrap capacitor charging for efficiency. Despite the TriC3? being a type of constant-current drive, it enables 100 % PWM Duty Cycle and high-impedance by trickle charge pumping.
