If no distortion can be observed in the output current waveform, the DCY pin should be kept High. The distortion
reduction depends on the motor characteristics. If any distortion can be observed, the DCY pin should be kept Low.
Also, it should be ensured that the DCY input is set High only when the coil of a motor has an inductance of 1.5 mH
or higher where fosc is no less than 100 kHz.
Thermal Shutdown (TSD) Circuit
The TB6608FNG includes a thermal shutdown circuit, which turns the output transistors off when the junction
temperature (Tj) exceeds 160°C (typ.).
The output transistors are automatically turned on when Tj cools past the shutdown threshold, which is lowered
by a hysteresis of 40°C.
TSD = 160°C (design target value)
ΔTSD = 40°C (design target value)
* In thermal shutdown mode, the internal circuitry and outputs assume the same states as in Enable Wait mode.
Upon exit from thermal shutdown mode, they revert to those states which they assume when taken out of
Enable Wait mode.
