TB67S559FTG
7. Functional Description 7.1. Function of SLEEP_X
The output can be recovered from the forced OFF state due to the operation of the thermal shutdown circuit (TSD)/overcurrent detection circuit (ISD) by setting the device to sleep mode once and then setting it to normal operation mode again. By setting SLEEP_X = Low, the device enters power-saving mode after 100 μs . High is input, the device returns to normal operation in 10 ms (max.)
Table 7.1 Function of SLEEP_X
SLEEP_X Function L Power saving mode (charge pump stopped, VCC Reg stopped) H normal operation
7.2. Function of CLK
Each CLK advances the electric angle by one, and the signal is reflected on the Up edge.
Table 7.2 Function of CLK
CLK Function ↑ Take the next step with an up-edge ↓ -(Hold previous state)
7.3. Function of ENABLE
Switches stepping motor drive ON/OFF. Turning the motor drive ON starts normal constant current control, and setting it to OFF turns the MOSFET OFF and the output is high impedance.
Table 7.3 Function of ENABLE
ENABLE Function H Output MOSFET operation : ON (normal operation) L Output MOSFET operation : OFF (operation stopped, high impedance)
7.4. Function of CW/CCW
Switches the direction of rotation of the stepping motor.
