Note: For lithium ion battery charging control (1-2 cells) For mobile telephones and other cases in which high

frequency noise could be a problem, we recommend lowering impedance by adding 33pF capacitance

between the VREF pin and GND, between the CS pin and GND, and between external PNP TR base and GND.

Please make sure that the wiring on the pattern is kept as short as possible. When implementing noise

countermeasures, be sure to consider the set as a whole.

Applicable circuits shown are typical examples provided for reference purposes. Mitsumi cannot assume

responsibility for any problems arising out of the use of these circuits or for any infringement of third party

patent and other right due to same.
