STK6712BMK4 Key Features
- This IC has the features of the STK6712BMK3, plus a simultaneous input prevention circuit that protects the IC from any
- Self-excitation design means chopping frequency is determined by motor L and R. Supports chopping at 20 kHz or higher
- Very low number of external ponents required
- Wide operating supply voltage range (V CC1 = 18 to 42V)
- Excitation sequence signal is active low, and is TTL level for direct interfacing to the microputer and gate array
- The unipolar design enables use as a driver for hybrid, PW, or VR type stepping motors
- Supports W1-2 phase operation, with a dual Vref pin
