MITSUBISHI <CONTROL / DRIVER IC>
M54641L/FP
Bi-DIRECTIONAL MOTOR DRIVER WITH BRAKE FUNCTION
Though the IC is equipped with a thermal shutdown circuit for
prevention against thermal breaking, the threshold temperature is
set to 100°C min. Set the driving current in such a way that this
thermal shutdown circuit cannot operate during normal operation.
