  • The L6228Q is a DMOS fully integrated stepper motor driver with non-dissipative overcurrent protection, realized in BCDmultipower 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 VFQFPN32 5 mm x 5 mm package, the L6228Q features a non-dissipative overcurrent protection on the high side power MOSFETs and thermal shutdown.

    Key Features

    • Operating supply voltage from 8 to 52 V
    • 2.8 A output peak current (1.4 A RMS)
    • RDS(on)0.73 Ω typ. value @ TJ = 25 °C
    • 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
    • Decoding logic for stepper motor full and half step drive
    • Cross conduction protection
    • Thermal shutdown
    • Undervoltage lockout
    • Integrated fast free wheeling diodes
