TB67S581FNG(O,EL) is a BiCD constant current two-phase bipolar stepping motor driver IC using a PWM chopper. Fabricated with the BiCD process, the TB67S581FNG rating is 50V/2.5A. The built-in regulator for IC operation allows the motor to be driven by a single VM power supply. It features built-in thermal shutdown detection (TSD), overcurrent detection (ISD), and undervoltage lockout detection (UVLO).
- BiCD process integrated monolithic IC capable of controlling bipolar stepping motor
- Decay modes select function (mixed decay / slow decay / fast decay)
- Power save function (sleep mode), clock input control
- 3.3V regulator output, allows full, half, quarter, 1 / 8, 1 / 16, 1 / 32 step operation
- BiCD structure: DMOSFET is used for output power transistor
- High breakdown voltage and large current: 50V / 2.5A (absolute maximum ratings)
- Error detection flag output function (nFAULT)
- Decreasing number of external components by reducing charge pump
- 8.2V to 44V motor power supply, 2A motor output current
- Operating temperature range from -40 to 85°C, HTSSOP28 package
