DESCRIPTION:

The MSK541 is a high power monolithic amplifier ideally suited for high power amplification and magnetic deflection

applications. This amplifier is capable of operation at a supply voltage rating of 80 volts and can deliver guaranteed

continuous output currents up to 5A, making the MSK541 series an excellent low cost choice for motor drive circuits.

The amplifier and load can be protected from fault conditions through the use of internal current limit circuitry that can be

user programmed with a single external resistor. The MSK541 is pin compatible with popular op-amps such as the Burr-

Brown OPA501, OPA511, OPA512, OPA541 and 3573. The MSK541 is available in a hermetically sealed 8 pin TO-3

package. The MSK145 is available in a 6 pin SIP Package. The MSK146 is an 8 pin Power DIP Package and the MSK147

is available in an 8 pin Power Z-TAB Package for applications requiring bolt down heat sinking. Other package styles are

also available for a wide range of applications.

APPLICATION NOTES

HEAT SINKING

CURRENT LIMIT

To select the correct heat sink for your application, refer to the

thermal model and governing equation below.

The MSK541 has an on-board current limit scheme designed

to limit the output drivers anytime output current exceeds a

predetermined limit. The following formula may be used to de-

termine the value of the current limit resistance necessary to

establish the desired current limit.

Thermal Model:

RCL (OHMs) = (0.809 volts / current limit in amps) - 0.057 OHM

The 0.057 OHM term takes into account any wire bond and

lead resistance. Since the 0.809 volt term is obtained from the

base emitter voltage drop of a bipolar transistor, the equation

only holds true for operation at +25°C case temperature. The

effect that temperature has on current limit may be seen on the

Current Limit vs. Case Temperature Curve in the Typical Perfor-

mance Curves.

Current Limit Connection

Governing Equation:

TJ = PD X (RθJC + RθCS + RθSA) + TA

Where

information on current limit connections.

Example: (TO-3 PACKAGE)

POWER SUPPLY BYPASSING

In our example the amplifier application requires the output to

drive a 20 volt peak sine wave across a 5 ohm load for 4 amps of

output current. For a worst case analysis we will treat the 4 amps

peak output current as a D.C. output current. The power supplies

are ±35 VDC.

Both the negative and the positive power supplies must be

effectively decoupled with a high and low frequency bypass

circuit to avoid power supply induced oscillation. An effective

decoupling scheme consists of a 0.1 microfarad ceramic ca-

pacitor in parallel with a 4.7 microfarad tantalum capacitor from

each power supply pin to ground. It is also a good practice

with very high power op-amps, such as the MSK541, to place

a 30-50 microfarad nonelectrolytic capacitor with a low effec-

tive series resistance in parallel with the other two power sup-

ply decoupling capacitors. This capacitor will eliminate any peak

output voltage clipping which may occur due to poor power

supply load regulation. All power supply decoupling capaci-

tors should be placed as close to the package power supply

pins as possible (pins 3 and 6 for the MSK541).

1.) Find Power Dissipation

PD = [(quiescent current) X (+VCC - (VCC))] + [(VS - VO) X IOUT]

= (30 mA) X (70V) + (15V) X (4A)

= 2.1W + 60W

= 62.1W

2.) For conservative design, set TJ = +150°C

3.) For this example, worst case TA = +25°C

4.) RθJC = 1.2°C/W typically for the TO-3 package

5.) RθCS = 0.15°C/W for most thermal greases

6.) Rearrange governing equation to solve for RθSA

RθSA

= (TJ - TA) / PD - (RθJC) - (RθCS)

= (150°C - 25°C) / 62.1W - (1.2°C/W) - (0.15°C/W)

= 0.66°C/W

SAFE OPERATING AREA

The safe operating area curve is a graphical representation

of the power handling capability of the amplifier under various

conditions. The wire bond current carrying capability, transis-

tor junction temperature and secondary breakdown limitations

are all incorporated into the safe operating area curves. All ap-

plications should be checked against the S.O.A. curves to

ensure high M.T.B.F.

The heat sink in this example must have a thermal resistance of

no more than 0.66°C/W to maintain a junction temperature of no

more than +150°C. Since this value of thermal resistance may be

difficult to find, other measures may have to be taken to decrease

the overall power dissipation.

Replacing OPA501 with MSK541

Motor Current a Function of VIN

Programmable Torque Circuit

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.

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.
