Table 5.
1. Accuracy depends on oscillator frequency accuracy.
2. Tested at 25 °C in a restricted range and guaranteed by characterization.
3. Rise and fall time depends on motor supply voltage value. Refer to SR
4. Not valid for the STBY/RST pin which has an internal pull-down resistor.
5. Not valid for the SW and CS pins which have an internal pull-up resistor.
6. FLAG, BUSY and SYNC open drain outputs included.
