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

Sunday, July 17th, 2016

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....

Power playground project

Thursday, February 19th, 2015

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...

Precise analog voltage from PWM

Monday, March 17th, 2014

Destate9  writes: So I've been trying to make a constant current H-bridge circuit for a project, and I'm running into trouble with PWM. Right now, all I have connected to the Output compare pin of my PIC32MX microcontroller is a 330uF capacitor (Max ESR of 1.4 ohms according to datasheet)....
