L6228PD Datasheet

Motor / Motion / Ignition Controllers & Drivers


The L6228PD is a DMOS Fully Integrated Stepper Motor Driver with non-dissipative Overcurrent Protection,realized in MultiPower-BCD technology, which combines is olated 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 L6228PD features a non-dissipative overcurrent protection on the high side Power MOSFETs and thermal shutdown. L6228PD Features • Operating supply voltage from 8 to 52v• 2.8a output peak current (1.4a rms)• Rds(on) 0.73w typ. value @ tj = 25°c• Operating frequency up to 100khz• 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• Under voltage lockout• Integrated fast free wheeling diodes L6228PD Applications • Bipolar stepper motor
