Four H-bridge drivers capable of PWM constant-current control
Supports up to two two-phase bipolar stepping motors (STMs) or up to four actuators.
Each channel is individually configurable for either H-Bridge mode or STM µStep mode via the serial
interface.
In STM µStep mode, the microstepping resolution is selectable from 6 bits (256 steps per full cycle) or 1 bit (8
steps per full cycle).
One PWM constant-current driver
The constant-current reference voltage (Vref) is programmable via the internal 6-bit DAC.
Each channel has a DAC for setting constant-current values (Channels A to D = 2 bits in H-Bridge mode and 2
bits × 6 bits in µStep mode; Channel E = 6 bits)

... When high-side output transistors are turned off, the TB6613FTG, by default, counts four rising edges of the internal clock signal as a turn-off period. (The counter resets at the fifth rising edge of the clock.) Based on this turn-off period, the TB6613FTG generates a PWM signal that turns on and off the output transistors. ...

... V) 2-bit DAC • Pulse clock control: The TB6613FTG steps up the current at each rising edge of the clock input to the PWMA/CK1 (for channels A and B) or PWMC/CK2 (for channels C and D) pin. (Current step-ups actually occur synchronous to the internal clock signal derived from MCK.) • ...

... Vref depending on the time constant of a motor coil, thus leading to a big distortion from the desired output current waveform. To improve the matching between the output current and the target current level, the TB6613FTG enters Fast-Decay mode very briefly immediately after each Vref step-down. In this mode, the output current recirculates back to the power supply ...

Otherwise, the current or power consumption may exceed the absolute maximum rating, and exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion.

... If the current sink capability of the power supply is small, the device’s motor power supply and output pins might be exposed to conditions beyond maximum ratings. To avoid this problem, take the effect of back-EMF into consideration in system design. 27 TB6613FTG 2008-06-27 ...
