TB67H481FNG(O,EL)

TB67H481FNG(O,EL) is a BiCD constant current dual H-bridge driver IC for driving 2 brushed motors / 1 stepping motor. Fabricated with the BiCD process, output rating is 50 V/2.5A. The built-in regulator for IC operation allows the motor to be driven by a single VM power supply. It features thermal shutdown detection (TSD), overcurrent detection (ISD), and under voltage lockout detection (UVLO).

• BiCD process integrated monolithic IC, two built-in H-bridge for output
• Decay modes select function (mixed decay / slow decay / fast decay)
• Power saving function (sleep mode), PWM constant current drive, 3.3V regulator output
• 3.3V regulator output, BiCD structure: DMOSFET is used for output power transistor
• High breakdown voltage, large current: 50V / 2.5A (absolute maximum rating)
• Error detection flag output function (LO)
• Reduction of external parts for charge pump
• 8.2V to 44V motor power supply, 2A motor output current
• Operating temperature range from -40 to 85°C, HTSSOP28 package
