4-Channel BTL Driver for Players
The CMD6392FP is a 4-channel BTL driver for CD player 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.
FApplications
www.DataSheetC4DU.pcolamyers, CD-ROM drives
FFeatures
1) HSOP 28-pin package allows for miniaturization of
applications.
2) PWM input is filtered by the internal primary filter,
eliminating the need for attached resistors and ca-
pacitors, thereby helping reduce the number of com-
ponents. Resistor and capacitor time constants can
also be changed with attached components.
3) Internal thermal shutdown circuit.
4) Internal mute circuit.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)

FCircuit operation
(1) Fig. 3 shows the inputs from the digital servo IC for
CH1-CH3 drivers (all drivers except the spindle).
SW1 is on when the forward input signal (HIGH level,
over 2.4V) is present. SW2 is on when the reverse input
signal is present (Fig. 2)
The constan current (I1)at this time enters the RC and
generates an integral waveform based on the duty of the
input waveform. The BTL is output from BUF1 and BUF2
(Fig. 4).
To maintain the HIGH level with forward (or reverse) in-
put, the DC voltage generated at point A is :
I1 R 2.5V (reverse : *2.5V)
This is the voltage generated relative VREF. The setting is
such that a voltage differential of 5V is generated be-
tween output pins. The time constant is :
R C = 2.4µsec
* All specs and applications shown above subject to change without prior notice.
