TA8411L

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: 4.30 g (typ.) Features CMOS-compatible input level (built-in pull-down resistor) Two built-in biphase, bipolar stepping motor drivers (bipolar driving and chopper type) Built-in push-pull driver Built-in register reset circuit Operating output voltage range: VM = 0 to 27 V Operating supply voltage range: VCC = 4.5 to 5.5 V TA8411L 1 2003-08-22 Block Diagram TA8411L Note 1: Capacitance connect to each Power Supply Terminal is required to change to optimum value for noise elimination and also required to connect directly to each Power Supply Terminal (VCC, VM1, 2) and the corresponding GND Terminal (See Table 1) for stable operations.
