Instructions and Precautions
.
Connect a capacitor of 1000 pF across pins 1 and 2 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 2 and 3.
DUAL Printed Circuit Pattern Example
.
Short Circuit Tests
Sanyo’s recommended printed circuit board: Apply VCC = 13.2 V using a 30 × 30 × 1.5 mm
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.
