FEATURES
● An ultra-fine CMOS process has been adopted for low power consumption in a design.
● A small 40-pin QFN package(5mm×5mm, lead pitch is 0.4 mm)has been adopted.
● 1ch/2ch and 3ch/4ch are capable of micro-steps mode. Possible modes are from 2-2 phase stepper drive to maximum 256 resolution micro-steps.
● Built-in autonomous drive circuit under the control of serial settings.
● Built-in 3-ch PI driver
● Under voltage lockout circuit
- Shut down the internal circuit at VCC=1.8V (Typ.)
● Thermal shut down circuit
- Shut down the internal circuit at 150℃ Hysteresis 30℃
● Power supply systems are all internally isolated and include a function to prevent reverse current between power supplies.
● Built-in exclusive control mode from channel 3 to channel 6.(resemblance 7 channel motor drive application)
● Package Type - QFN 40
