Application Circuit
Note 1: Connect a Schottky diode (Toshiba 2GWJ42 or equivalent) for pass-through current prevention between
each of the two outputs and a ground.
Note 2: When turning on the power for the IC, raise V
S
after V
CC
has been raised to its rated level (or V
CC
and V
S
simultaneously). When shutting off the power, drop V
CC
after V
S
(or V
S
and V
CC
simultaneously).
Note 3: Keep the control pins (IN, BRAKE, ENABLE, and CHOP) low before the supply voltage V
CC
has been raised
to its rated level. (Alternatively, raise all these voltages simultaneously.)
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 maximum rating, breakdown
may occur before the protection circuit starts operating.
Note 6: Utmost care is necessary in the design of the output line, V
CC
, V
S
, and GND line since the IC may be
damaged due to short circuits between outputs, supply faults, or ground faults.
