MSK541_15 Datasheet, PDF (4/8 Pages) M.S. Kennedy Corporation – High Output Current - 10 Amps Peak

APPLICATION CIRCUITS
Clamping Output for EMF-Generating Loads
Isolating Capacitive Loads
Motor Current a Function of VIN
Programmable Torque Circuit
The linear relationship of torque output to current input
of the modern torque motor makes this simple control cir-
cuit ideal for many material processing and testing appli-
cations. The sense resistor develops a feedback voltage
proportional to motor current and the small signal proper-
ties of the Power Op Amp insure accuracy. With this closed
loop operation, temperature induced impedance variations
of the motor winding are automatically compensated.
Replacing OPA501 with MSK541
When replacing the OPA501, OPA511, OPA512 or 3573
with the MSK541, it is not necessary to make any changes
in the current limit scheme. Since pin 2 is not connected in
the MSK541, the current limit resistor connected from pin
1 to pin 2 can be left in the circuit or removed.
