Usage Notes

Notes on the V
REF
pin
Since the V
REF
pin inputs the reference voltage used to set the current, applications must be designed so that noise
does not occur at this pin.
x
Notes on the ground pins
Since this IC switches large currents, care is required with respect to the ground pins.
The PCB pattern in sections where large currents flow must be designed with low impedances and must be kept
separate from the small-signal system.
In particular, the ground terminals of the E1 and E2 pin sense resistors (RE) and the external Schottky barrier diode
ground terminals must be located as close as possible to the IC ground. The capacitors between V
CC
and ground and
between V
BB
and ground must be as close as possible to the corresponding V
CC
and V
BB
pin in the pattern.

Note that if the power supply for the logic level inputs is on when the V

power supply is off, a bias with an
unstable state will be applied due to the protection diodes at the V
CC
pins, and this can cause incorrect operation.
Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer's
