Features & Applications
The L6228DTR is a DMOS Fully Integrated Stepper Motor Driver with non-dissipative Overcurrent Protection, realized in MultiPower-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.
Features:
- Operating supply voltage from 8 to 52 V
- 2.8 A output peak current (1.4 A DC)
- 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 CurrentControllers
- Fast/Slow Decay Mode Selection
- Fast Decay Quasi-Synchronous Rectification
- Decoding Logic for Stepper MotorFull And Step Drive
- Cross conduction protection
- Thermal shutdown
- Undervoltage lockout
- Integrated fast free wheeling diodes
Applications:
- Bipolar Stepper Motor
