App note: Parallel configuration of H-bridges featuring the MC33932 and MC34932 ICs

Old application note from ON Semiconductors on getting increased power capability by paralleling H-bridges and overcoming current limit imbalance between the two drivers by properly designing the board layout. Link here (PDF) Two or more H-bridges can be operated in parallel to increase the current handling capacity of the circuit. In this application note, paralleling […]

Power playground project

Spacewrench over at Dorkbotpdx published a new build, a Power Playground project: It’s a PMOS/NMOS H-Bridge with FETs that can handle 3 amps or so, plus a SPI current sensor, some switches & a rotary encoder (not stuffed yet), and a 7-segment display, all controlled by a Teensy-3.1 running FreeRTOS. I made this because I’m always running into battery, […]
