The LA6245P is a 4channel motor driver IC for home and car CD players. It provides a pin for switching the channel 1
input.
• Four bridge-connected (BTL) power amplifier circuits.
• I O max: 1A.
• Built-in level shifter circuits.
• Muting circuit (on/off control for all outputs).
• Independent operational amplifier.
• Variable regulator (uses an external pnp transistor for output).
• Regulator includes an on/off switching function.
• Thermal shutdown operation monitor pin.
Parameter
Any and all SANYO Semiconductor products described or contained herein do not have specifications
that can handle applications that require extremely high levels of reliability, such as life-support systems,
aircraft's control systems, or other applications whose failure can be reasonably expected to result in
serious physical and/or material damage. Consult with your SANYO Semiconductor representative
nearest you before using any SANYO Semiconductor products described or contained herein in such
applications.
SANYO Semiconductor 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
products described or contained herein.
