FEATURES: Available as SMD #5962-8508801 High Output Current - 2 Amps Peak Low Power Consumption-Class C Design Programmable Current Limit High Slew Rate Continuous Output Short Circuit Duration Replacement for LH0021 Functionally Equivalent Rad Hard Device MSK106RH DESCRIPTION: The MSK0021, 0021FP and 0021FPG are general purpose Class C power operational amplifiers. These amplifiers offer large output currents, making them an excellent low cost choice for motor drive circuits. The amplifier and load can be pro- tected from fault conditions through the use of internal current limit circuitry that can be user programmed with two external resistors. These devices are also compensated with a single external capacitor. The MSK0021 is available in a hermetically sealed 8 pin TO-3 package. The MSK0021FP is packaged in a 20 pin hermetic metal flatpack and the 0021FPG is lead formed by MSK.

To select the correct heat sink for your application, re - fer to the thermal model and governing equation below. Thermal Model: APPLICATION NOTES CURRENT LIMIT The MSK0021 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 determine the value of the current limit resis - tance necessary to establish the desired current limit. Current Limit Connection RSC= 0.7 ISC ___ See "Application Circuits" in this data sheet for ad - ditional information on current limit connections. POWER SUPPLY BYPASSING 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 high power op-amps, such as the MSK0021, to place a 30-50 microfarad capacitor with a low effective series resistance, in parallel with the other two power supply 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 capacitors should be placed as close to the package power supply pins as possible. 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, transistor junction temperature and secondary breakdown limitations are all incorporated into the safe operating area curves. All applications should be checked against the S.O.A. curves to ensure high M.T.B.F. Governing Equation: TJ = PD X (RθJC + RθCS + RθSA) + TA Where T J = Junction Temperature P D = Total Power Dissipation R θJC = Junction to Case Thermal Resistance R θCS = Case to Heat Sink Thermal Resistance R θSA = Heat Sink to Ambient Thermal Resistance T C = Case Temperature T A = Ambient Temperature T S = Sink Temperature Example: (TO-3 PACKAGE) In our example the amplifier application requires the output to drive a 10 volt peak sine wave across a 10 ohm load for 1 amp of output current. For a worst case analysis we will treat the 1 amp peak output current as a D.C. output current. The power supplies are ±15 VDC. 1.) Find Power Dissipation P D=[(quiescent current) X (+VCC- (-VCC))] + [(VS - VO) X IOUT] =0.1W + 5W =5.1W 2.) For conservative design, set TJ = +125°C. 3.) For this example, worst case TA = +25°C. 4.) RθJC = 2.0°C/W typically for the TO-3 package. 5.) Rearrange governing equation to solve for RθSA: R θSA = (TJ - TA) / PD - (RθJC) - (RθCS) = 17.5°C/W The heat sink in this example must have a thermal resistance of no more than 17.5°C/W to maintain a junction temperature of less than +125°C. 8548-83 Rev.
