PWMMotor Interface
Comments on Schematic
The following schematic shows a typical interface circuit between the
MC1241A and an amplifier which accepts an analog curent command
and a separate sign bit.
The A3952 fromAllegro Mcrosystems is an integrated H-bridge
package with internal current loop control which provides all TTL and
power-level circuitry to forma complete amplifier-on-a-chip. The only
other components needed are capacitors and resistors.
The analog current command input to the amplifier chip is constructed
by low pass filtering the digital magnitude output signal fromthe
chipset. The sign bit is connected directly fromthe MC1241A chipset to
the amplifier.
The amplifier performs the current control by continuously compariing
the analog input signal fromthe chipset (current command) to the
measured current and turing on or off the H-bridge drivers accordingly
to maintain the actual current close to the desired current.
Some of the resistor and capacitor values for the circuit may need to be
adjusted depending on the partricular values for the motor resistance
and inductance. In particular the value shown for R7 (.175 Ohm may
change if a maximumcurrent of less than 2 Amps is desired. Other
values which may be adjusted are R1 and C1. These adjust the overall
PWMfrequency (off-time duration) as well as the blanking intervale.
See the Allegro application notes for more information.
