Pin Description IXMS 150
Nomenclature of Dual PWM
Microstepping Controller
Sym. Pin Description
AGND 1 Analog Ground
COMP 2 Analog Compensation

5 recommendations).

VIN
3 Analog Input: The analog
22 input range is ± 2 V. A low
output im pedance voltage
source should drive these
pins. The input is greater
than 20 kΩ.
SENSE 6 Analog Sense: Each of the
19 phases sense resistors are
connected to these pins.
Input range is +0.625 V.
FFWD 7 FFWD, for Motor High
Voltage Compensation: A
voltage on this pin sets the
oscillator amplitude. Input
range = 0.9-4 V (see
application notes for
recommendations).
BY-
8 Filter Cap: A capacitor on
PASS
this pin provides filtering to
the internal bias network.
VOUT 9 Output Stage: To drive
10 buffered power MOSFET
15 H-Bridge.
16
VBB
11 Negative Bias Generator
Output: For internal use by
the IXMS 150.
DGND 12 Digital Ground
CPUMP 13 Charge Pump Capacitor:
Used by the internal
Negative Bias Generator.
OUTDIS 14 Digital ENABLE input and
STATUS output: Forcing this
pin low causes pins 9, 10,
15, and 16 to go low, disab-
ling the H-bridge. When uses
as an output, a low state on
this pin indicates an over
current, excess current, or
insufficient +V
DD or VBB error
condition.

17 Oscillator Frequency and
18 Dead-time set: Independent
adjustment can be made to
the oscillator frequency and
dead-time (see applications
notes).
VDD
24 Positive Supply Voltage
* Pin numbers in parantheses are
associated with channel B.
