IN8510 and power motor driver circuit composed of DAC7520

Posted on Mar 28, 2007

BTS412B as two high-side power MOSFET switch and two BU271L 50v for the low-side switch, can be composed of bi-directional H-bridge DC motor drive circuit shown in Figure 11-1l. The circuit is an electrical automatic doors design, continuous current up to 6A.

Four-leg switches are directly controlled by CMOS logic levels. Two BTS412B state output of the logical drive or a transistor, the LED displays the fault status. Left leg midpoint -to-ground resistance when 12ktl four H-bridge switches are turned off, will not be BTS412B mistaken Open load. Once open load occurs, the right of BTS412B can detect it and issue a fault signal.
