USING MOSFET DRIVERS FOR MOTOR DRIVES
In motor drive systems, a gate driver or “pre-driver” IC is often used along with N-channel power MOSFETs to provide the high current needed to drive motors. There are a number of design considerations to be made when selecting the driver IC, MOSFETs, and in some cases associated passive components. Often this process is poorly understood, and implementations are less than optimal. Th...

MAGNETIC ANGLE SENSORS: RESOLUTION EXPLAINED
Because optical encoders are functionally similar, “resolution” is often used as a main characteristic for magnetic encoders (a device providing the angle of a magnet attached to a mechanical shaft, under a digital form). Resolution is a key parameter since it indicates the smallest angle that the sensor is capable of resolving. Unfortunately, when comparing products, users may often be misled, as...
