This Design Idea shows how to use a 63¢ (Q=1) microprocessor reset voltage detector IC in a relay coil drive circuit to greatly reduce the coil’s hold-in current. When asked to estimate the coil ...

The MPS MP6500 stepper driver IC, which uses internal current sensing and the current regulation scheme described above, provides considerably better motion quality. The speed variation, while not ...

Figures 2a-c compare IC-VM, IC-CM and IC-HM with a transient from 500 mA to 5 A, then back to 500 mA at 5V and 12V input voltage settings. Figures 2b and 2c zoom in on the plot shown in Fig. 2a . 2a.

Short circuit current ratings should not be overlooked during panel design. Negative impacts can occur to production, equipment and, worst case, plant personnel. Per 2014 NEC Article 100, short ...

Allegro MicroSystems Europe has unveiled a three-phase brushless BLDC motor controller for use with N-channel external power MOSFETs. The AMT49413 incorporates much of the circuitry required to design ...
