Features

Low noise during Motor Hold with external PWM excitation

This series utilizes an external excitation (fixed frequency) PWM method for constant current control. Conventional self-excitation methods feature a timing lag between channels between regeneration and output ON, resulting in noise. Conversely, ROHM's high voltage stepping motor drivers utilize external excitation with synchronized timing, reducing noise significantly.

Current attenuation switching possible via 2bit logic input
Easy board layout with simple CLK IN control(BD6425EFV, BD6423EFV)
Ultra-thin, compact size and high heat dissipation characteristics simplify thermal design - even with large currents(BD6425EFV, BD6424EFV [HTSSOP-B28] BD6423EFV, BD6422EFV [HTSSOP-B24])
High 42V drive
