High Performance Dual PWM Microstepping Controller
Type
IXMS150 PSI
Package
24-Pin Skinny DIP
Temperature Range
-40°C to +85°C
The IXMS150 is a high performance
monolithic 2-channel PWM controller.
Implemented in CMOS, the low power
IXMS150 precisely controls the current
in each of two separate power H-bridge
drivers using unique sampling and
www.DataSheets4iUgn.caolmprocessing techniques. Each
channel contains an error amplifier,
PWM, feedback amplifier, and protec-
tion circuitry. Protection features include
over/excess current shutdown, min/max
duty cycle clamp, under voltage lock-
out, dead time insertion, and a shutdown
input for over-temp or other external
fault circuitry. Other features include a
common oscillator, feedforward circuit
for motor supply compensation, and an
onchip negative bias generator.
The IXMS150 has been optimized for
microstep control of two phase step
motors. Due to its high level of accu-
Block diagram of IXMS 150
racy, the IXMS150 will allow a designer
to implement a control system with a
resolution in excess of 250 microsteps
per step, or 50,000 steps per revolution
with a 200 step per revolution step
motor. The IXMS150 greatly improves
positioning accuracy and virtually
eliminates low speed velocity ripple and
resonance effects at a fraction of the cost
of a board level microstepping system.
Other applications which the IXMS150
is designed for include control of two
single-phase (DC) motors or control of
synchronous reluctance motors. The
IXMS150 is ideal for robotics, printers,
plotters, and x-y tables and can facilita-
te the construction of very sophisticated
positioning control systems while signi-
ficantly reducing component cost, board
space, design time and systems cost.
