ML4411/ML4411A
APPLICATIONS
Figure 10 shows a typical application of the ML4411 in a
hard disk drive spindle control. Although the timing
necessary to start the motor in most applications would be
generated by a microcontroller, Fig. 11 shows a simple
“one shot” start-up timing approach.
Speed control can be accomplished either by:
1. Sensing the VCO OUT frequency with a
Microcontroller and adjusting ICMD via an analog
output form the Micro (PWM DAC).
2. Using analog circuitry for speed control. (Fig. 12).
OUTPUT STAGE HINTS
In the circuit in Figure 10, Q1, Q2, and Q3 are IRFR9024
or equivalent. Q4, Q5, and Q6 are IRFR024 or equivalent.
New MOSFET packaging technology such as the Little
Foot“ series may decrease the PC board space. These
packages, however have much lower thermal inertia and
dissipation capabilities than the larger packages, and care
should be taken not to exceed their rated current and
junction temperature.
Since the output section in a full bridge application
consists of three half-H switches, cross-conduction can
occur. Cross-conduction is the condition where an N-FET
and P-FET in the same phase of the bridge conduct
simultaneously. This could happen under two conditions
