TOSHIBA Bi-CD Integrated Circuit Silicon Monolithic TB6559FG Full-Bridge DC Motor Driver IC TB6559FG The TB6559FG is a full-bridge DC motor driver with LDMOS output transistors. It uses P-channel MOSFETs on the high side and N-channel MOSFETs on the low side, eliminating the need for a charge pump. The TB6559FG achieves high thermal efficiency. Four operating modes are selectable via IN1 and IN2: clockwise (CW), counterclockwise (CCW), short brake and stop. Features • Power supply voltage: 50 V (max) • Output current: 2.5 A (max) • Low-ON resistance (upper and lower sum): 1.3 Ω (typ.) • Constant-current or direct PWM • Standby mode • Clockwise (CW), counterclockwise (CCW), short brake and stop • Overcurrent protection • Thermal shutdown Weight: 0.50 g (typ.
