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.

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 +VDD 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.
