UTC UA9392 LINEAR INTEGRATED CIRCUIT
4-CHANNEL BTL DRIVE
FOR CD PLAYERS
DESCRIPTION
The UTC UA9392 is a 4-channel BTL driver for CD plsyer
motors and actuators. It has an internal primary filter, and
can be directly connected (without attached components)
to the servo PWM output of all drivers other than the
spindle driver.
FEATURES
*PWM input is filtered by the internal primary filter,
eliminating the need for attached resistors and capacitors,
thereby helping reduce the number of components.
Resistor and capacitor time constant can be changed with
attached components.
*Internal mute circuit.
*Thermal shutdown circuit is contained.
*Level-shift circuit is contained.
