L6258 General Description
L6258 is a dual full bridge for motor control appli-
cations realized in BCD technology, with the ca- pability of driving both windings of a bipolar step- per motor or bidirectionally control two DC motors.
L6258 and a few external components form a complete control and drive circuit. It has high effi- ciency phase shift chopping that allows a very low current ripple at the lowest current control levels, and makes this device ideal for steppers as well as for DC motors.
The power stage is a dual DMOS full bridge capa- ble of sustaining up to 45V, and includes the di- odes for current recirculation.
The output current capability is 1.5A per winding in continuous mode, with peak start-up current up to 2A.
A thermal protection circuitry disables the outputs if the chip temperature exceeds the safe limits.
