Setup Condition a. Adjust the power supply VIN with recommended operating range (7V to 28V). b. Input for VCC power supply is on board (5V or 3.3V, use SW1 to adjust). c. Easy adaptation of loads by CN4 - CN7. d. EN alternatively connected to VCC or GND, selected by S8 of SW2. e. Serial data interface control via CN1 connectors. 3. Monitors a. For full-bridge application, indicate rotation direction of DC motors can be observed by LEDs if S1 – S5 of SW2 switches ON position. b. All pins are easily accessible via test points. c. A low output at FAULT indicates that the IC has detected an over-temperature or over-current condition. NOTICE: The information in this document is subject to change without notice.
