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.
