Brushed Motor Driver
DR70xQ is a automotive-grade H-bridge smart gate driver that, in conjunction with four external MOSFETs, can achieve bidirectional DC brush motor control. It is widely used in automotive applications such as electric tailgates, sunroofs, windows, doors, and EPB systems to drive DC brush motors ranging from a few watts to several hundred watts. DR70xQ has a maximum VM withstand voltage of 55V and is equipped with offline load detection and other system protection mechanisms, offering more flexible drive current control.
