There are easier-to-use alternatives to the thyristor (aka SCR) based mains fed motor controllers used to control ‘180Vdc’ brushed electric motors. These are mosfet choppers, but they tend to cost over £100 and are often poorly documented as they are made as drop-in replacements for treadmill motor controllers such as the MC2100ELS. Interfacing to them can also be tricky as ...
For brushed dc motors, Rohm has developed a pair of driver ICs. BD60210FV is for two 8 – 18V 1A motors (4A peak) and comes in a 5 x 6.4mm 16pad SSOP. It has a number of modes, including stand-by/forward/reverse over two wires, or stand-by/forward/reverse/brake over four wires, and as four half-bridges – to control a single two-phase stepper motor, ...
Infineon has released a family of H-bridge driver ICs for small brushed dc motors in vehicles, that include hardware for ISO26262-level functional safety. Called the BTM90xx family, they are intended to work over 7 to 18V, but have some function at 4.5V, and can survive up to 40V. There are four parts: BTM9010EP ±3.4A continuous, PWM input BTM9011EP ±3.4A continuous, ...
