TB6560AHQ:PWM chopper-type stepping motor driver IC

The TB6560AHQ/AFG is a PWM chopper-type stepping motor driver IC designed for sinusoidal-input microstep control of bipolar stepping motors. The TB6560AHQ/AFG can be used in applications that require 2-phase,1-2-phase,2W1-2-phase and

4W1-2-phase excitation modes. The TB6560AHQ/AFG is capable of low-vibration, high-performance forward and reverse driving of a two-phase bipolar stepping motor using only a clock signal.

• Single-chip motor driver for sinusoidal microstep control of stepping motors 

• High output withstands voltage due to the use of BiCD process: Ron (upper and lower sum) =TB6560AHQ: 0.6 Ω (typ.)                                                                                                                                                                TB6560AFG: 0.7 Ω (typ.) 

• Forward and reverse rotation 

• Selectable phase excitation modes (2,1-2,2W1-2 and 4W1-2)

• High output withstand voltage: VDSS = 40 V

• High output current: IOUT = TB6560AHQ: 3.5 A (peak)

TB6560AFG: 2.5 A (peak)

• Packages: HZIP25-P-1.27 

                   HQFP64-P-1010-0.50 

• Internal pull-down resistors on inputs: 100 kΩ (typ.)

• Thermal shutdown (TSD)

HR8828 and TB6608 are alternatives if TB6560AHQ. The following excel will introduce them for you.

Parameter comparison:

The operating temperature range represents the ability of the driver chip to work in extreme environments. The larger the absolute value is, the more extreme the driver chip can work in.HR8828 can replace TB6560AFG and TB6608 when the operating temperature range is from -20 ℃ to 85℃.

The load supply voltage and output drive current represent the output capacity of the motor driver chip.The HR8828 has a load supply voltage of 8-38V, TB6560AFG 4.5-34V,and TB6608 2.5-13.5V.Therefore, it can be replaced within the supply voltage range of 8-13.5V in the same voltage class; The HR8828 has A drive current of 3.5a, TB6560AFG 1.5A, and TB6608 0.8A (peak value), mainly driving some small motors. 

HR8828 is packaged with QFN48, TB6560AFG is packaged with HZIP25 or HQFP64, and TB6608 is packaged with SSOP20.TB6560AFG and TB6608 are old products with old packaging, so they need to be redesigned when replacing them with HR8828.

Toshiba Corporation ( Kabushikigaisha Toshiba) is a Japanese multinational conglomerate headquartered in Minato, Tokyo. Its diversified products and services include power, industrial and social infrastructure systems, elevators and escalators, electronic components, semiconductors, hard disk drives (HDD), printers, batteries, lighting, as well as IT solutions such as quantum cryptography.[3][4] It was one of the biggest manufacturers of personal computers, consumer electronics, home appliances, and medical equipment. As a semiconductor company and the inventor of flash memory, Toshiba had been one of the top 10 in the chip industry until its flash memory unit was spun off as Toshiba Memory, later Kioxia, in the late 2010s.

(1) Small motor vibration and low noise: because the chip comes with 2,8,16 subdivision optional, enough to meet the application requirements from a few revolutions to nearly 1000 revolutions per minute. 

(2) Less heat from the embedded driver: the heat dissipation area of the chip is enough to support the heat dissipation requirements of a small current drive alone. 

(3) Support a variety of stepper motor selection: customers can choose slightly larger torque hybrid or permanent magnet stepper motor, so that the motor works between 30 to 50 percent of the maximum allowable torque, the motor cost is almost unchanged;  The chip provides the multi-current setting and current attenuation mode, and supports stepper motors with different parameters under the same power index.
