Sample Application Circuit
Notes on Usage
1. External diodes
Because this IC uses upper-side transistor switching in SLOW DECAY mode and dual-side transistor switching in
FAST DECAY mode, it requires external diodes between the OUT pins and ground for the regenerative current during
switching OFF. Use Schottky barrier diodes with low VF.
2. V
REF
pin
Because the V
REF
pin serves for input of the set current reference voltage, precautions against noise must be taken. The
input voltage range is 0 to 3.0V.
3. GND pin
The ground circuit for this IC must be designed so as to allow for high-current switching. Blocks where high current
flows must use low-impedance patterns and must be removed from small-signal lines. Especially the ground connection
for the sensing resistor RE at pin E, and the ground connection for the Schottky barrier diodes should be in close
proximity to the IC ground.
The capacitors between V
CC
and ground, and V
BB
and ground should be placed close to the V
CC
and V
BB
pins,
respectively.
