TB67S580FNG(O,EL)

TB67S580FNG(O,EL) is a BiCD constant current two-phase bipolar stepping motor driver IC using a PWM chopper. Fabricated with the BiCD process, the TB67S580FNG rating is 50V/1.6A. 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), Over current detection (ISD), and Under voltage 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 / 1.6A (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
