PRODUCT SPECIFICATION
ML4425
REV. 1.0.2 7/2/01
3
Absolute Maximum Ratings
Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum
ratings are stress ratings only and functional device operation is not implied.
Operating Conditions
16
RVCO
An resistor to GND sets up a current proportional to the input voltage of the VCO.
17
CAT
A capacitor to GND sets the time that the controller stays in the align mode.
18
UV FAULT
This output goes low when VDD drops below the UVLO threshold, and indicates that
all output drivers have been disabled.
19
CRT
A capacitor to GND sets the time that the controller stays in the ramp mode.
20
SPEED FB
Output of the back-EMF sampling circuit and input to the VCO. An RC network
connected to SPEED FB sets the compensation for the PLL loop formed by the
back-EMF sampling circuit, the VCO, and the commutation state machine.
21
CRR
A capacitor to between CRR and SPEED FB sets the ramp rate (acceleration) of the
motor when the controller is in ramp mode.
22
FB A
The motor feedback voltage from phase A is monitored through a resistor divider for
back-EMF sensing at this pin.
23
FB B
The motor feedback voltage from phase B is monitored through a resistor divider for
back-EMF sensing at this pin.
24
FB C
The motor feedback voltage from phase C is monitored through a resistor divider for
back-EMF sensing at this pin.
25
BRAKE
A logic low input activates motor braking by shutting off the high-side output drivers
and turning on the low-side output drivers.
26
CIOS
A capacitor to GND sets the time that the low-side output drivers remain off after
ISENSE exceeds its threshold .
27
RREF
An 137k
Ω resistor to GND sets a current proportional to VREF that is used to set all
the internal bias currents except for the VCO.
28
GND
Signal and power ground.
