TN90002H-bridge motor controller design using Nexperia discretesemiconductors and logic ICsRev. 3 14 February 2020 Technical noteDocument informationInformationContentKeywordsH-b ridge, MOSFET, motor controllerAbstractAn example of a H-bridge motor controller designed with Nexperia discrete and Nexperia logic motor controller design using Nexperia discrete semiconductors and logic ICs1. IntroductionThis technical note demonstrates a H-bridge motor controller PCB, built using Nexperia discretesemiconductors and logic H-bridge circuit is a full bridge DC-to-DC converter allowing operation of a brushed DC motor (48 V max, 12 V min, 5 A max). The key feature of this design is that all electronic functions aredesigned with Nexperia discrete and logic IC components (low cost, no micro- controller or softwareneeded).MQ1Q2Q3Q4+V+Vaaa-030956 Fig. MOSFET H-bridge motor controlThe left MOSFETs of the full bridge (Q1 and Q3 in the simplified diagram above) are the switchingMOSFETs (see the PCB top view in Fig.)
