4-CH BTL DRIVER FOR CD PLAYER WITH 3.3V OUTPUT VOLTAGE

 

 

DESCRIPTION 

The SA1469PH, an IC for CD players, has a 4-channel BTL driver, 

3.3V regulator (attached PNP transistor required), standard operational 

amplifier, and internal reset output linked to an internal thermal shutdown 

circuit. The driver has gain adjustment input pins for each channel, 

allowing gain to be set to the desired value. Also, the internal level shift 

circuit helps reduce the number of attached components. 

 

 

 

FEATURES 

 1-phase, full-wave, linear DC motor driver 

 Gain is adjustable with an attached resistor. 

 Internal standard operational amplifier. 

 Internal 3.3V regulator. (required attached PNP transistor) 

 Internal thermal shutdown circuit with hysteresis capabilities.
