Application Circuit
Note 1: Connect a Schottky diode (Toshiba 2GWJ42 or equivalent) for pass-through current prevention between
Note 2: When turning on the power for the IC, raise V
Note 3: Keep the control pins (IN, BRAKE, ENABLE, and CHOP) low before the supply voltage V
Note 4: Insert a current limiting resistor (R) or fuse for over-current protection.
Note 5: The IC contains a thermal circuit breaker. However, if the IC operates over its absolute maximum rating,
Note 6: Utmost care is necessary in the design of the output, V
