SANYO Semiconductor Co.,Ltd. assumes no responsibility for equipment failures that result from using
products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition
ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor Co.,Ltd.
products described or contained herein.
SANYO Semiconductor Co.,Ltd. strives to supply high-quality high-reliability products, however, any and all
semiconductor products fail or malfunction with some probability. It is possible that these probabilistic failures or
malfunction could give rise to accidents or events that could endanger human lives, trouble that could give rise
to smoke or fire, or accidents that could cause damage to other property. When designing equipment, adopt
safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not
limited to protective circuits and error prevention circuits for safe design, redundant design, and structural
design.

Operation of the START-UP circuit
To operate the START-UP circuit during low-voltage operation, connect power supply to the VBATT pin and turn ON
CTL and STBY6 simultaneously. Firstly, at a time when the OC pin performs switching to raise VCC 2.3Vtyp or more,
the operation is changed over to OUT6 in the latched state. To cancel the latched state, either lower VCC to 0.95Vmin
or less or turn OFF STBY6 and CTL once. The START-UP circuit enters the operation state again.
The circuit is provided with the function that stops operation of the START-UP circuit when the VBATT pin is
2.35VTyp or more.
* Connect VBATT and OC pins to GND when the START-UP circuit is not to be used.
This catalog provides information as of February, 2007. Specifications and information herein are subject
