Product overview

Description

The L6228Q is a DMOS fully integrated stepper motor driver, realized in BCD multipower technology. The L6228Q includes the circuitry to drive a two-phase bipolar stepper motor: a dual DMOS full-bridge, the constant off-time, the PWM current controller performing the chopping regulation and the phase sequence generator, which generates the stepping sequence. The device features a non-dissipative overcurrent protection on the high-side power MOSFETs and thermal shutdown.
  • All features

    • Operating supply voltage from 8 to 52 V
    • 2.8 A output peak current (1.4 Ar.m.s.)
    • RDS(on)0.73 Ω typ. value @ TJ= 25 °C
    • Operating frequency up to 100 kHz
    • Non dissipative overcurrent protection
    • Dual independent constant tOFFPWM current controllers
    • Fast/slow decay mode selection
    • Fast decay quasi-synchronous rectification
    • Decoding logic for stepper motor full and half- step drive
    • Cross conduction protection
    • Thermal shutdown
    • Undervoltage lockout
    • Integrated fast free wheeling diodes
