TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8411L Biphase Bipolar Stepper and Push-Pull Driver The TA8411L incorporates drivers for bipolar stepping motors (chopper type) and a DC motor driver. Its input section is a serial input type and has a shift register with a 12-bit latch. Its output section has a push-pull driver that can supply up to 0.6 A and two sets of 8 bipolar drivers that can supply up to 0.8 A. It can control two bipolar stepping motors and one brushed motor or solenoid. The VM-AB, VM-CD, VM-E and VCC power supply voltages are independent of one another, and they can have any voltage relationship among them. Because the output section incorporates a circuit that can switch at high speed, it can support a PWM frequency of up to 200 kHz. Weight: 4.
