L6228DTR Bipolar Stepper Motor Driver Chip DMOS Parallel 24-SO

L6228DTR Bipolar Motor Driver DMOS Parallel 24-SO

Features:

●Operating supply voltage from 8 to 52 V

●2.8 A output peak current (1.4 A RMS)

●Operating frequency up to 100 KHz

●Non-dissipative overcurrent protection

●Dual independent constant tOFF PWM current controllers

●Fast/slow decay mode selection

●Fast decay quasi-synchronous rectification

Description:

The L6228 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 PowerSO36 and SO24 (20 + 2 + 2)

packages, the L6228 device features a non-dissipative overcurrent protection on the high-side power MOSFETs and

thermal shutdown.
