Instructions and Precautions
Connect a capacitor of 1000pF across pins
and
for external disturbance path.
Be careful of the ground line artwork when laying out the printed circuit pattern. Arrange so that the Sg route and load
current flow-in route do not overlap. Refer to the recommended printed circuit pattern or make slits, etc. at pins
and
.
DUAL Printed Circuit Pattern Example
Short Circuit Tests
SANYO Semiconductor's recommended printed circuit board: Apply VCC=13.2V using a 30×30×1.5mm
3 thick
aluminum board. The IC will be protected from the DC/AC shorting of switches 1 to 4 above. However, be careful not
to damage the IC by turning VCC ”ON” when DC short (SW 1 or SW 2) is on.
Power Supply Positive Surge
The over-voltage protector (VCCX ≈ 21.5V) inside the IC is used to cut all bias routes and reverse bias between B-E of
output stage elements, in order to increase the power line’s capability of handling positive surge. This means, of course,
that a VCES (VCBO) type output stage element is used instead of the VCEO (VCER) type.
