Description

The L6208 device is a DMOS fully integrated

stepper motor driver with non-dissipative

overcurrent protection, realized in BCD

technology, which combines isolated DMOS

power transistors with CMOS and bipolar circuits

on the same chip. The device includes all the

circuitry needed to drive a two phase bipolar

stepper motor including: a dual DMOS full bridge,

the constant off time PWM current controller that

performs the chopping regulation and the phase

sequence generator, that generates the stepping

sequence. Available in PowerDIP24 (20 + 2 + 2),

PowerSO36 and SO24 (20 + 2 + 2) packages, the

L6208 device features a non-dissipative

overcurrent protection on the high-side Power

MOSFETs and thermal shutdown.
