This amplifier offers high output currents, making it an excellent choice for motor drive circuits. It is the industry wide RAD HARD replacement for the LH0041. The amplifier and load can be protected from fault conditions through the use of internal current limit circuitry that can be user programmed with two external resistors. This device is also compensated with a single external capacitor. The MSK0041RH is available in a hermetically sealed 12 pin TO-8 package.

F 7/15 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 MSK0041RH 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 resistance necessary to establish the desired current limit. ___ 0.7 RSC= ISC Thermal Model: Current Limit Connection Governing Equation: TJ = PD x (RθJC + RθCS + RθSA) + TA Where TJ PD RθJC RθCS RθSA TC TA TS = = = = = = = = See "Application Circuits" in this data sheet for additional information on current limit connections. Junction Temperature Total Power Dissipation Junction to Case Thermal Resistance Case to Heat Sink Thermal Resistance Heat Sink to Ambient Thermal Resistance Case Temperature Ambient Temperature Sink Temperature POWER SUPPLY BYPASSING Example: In our example the amplifier application requires the output to drive a 10 volt peak sine wave across a 100 ohm load for 0.1 amp of output current. For a worst case analysis we will treat the 0.1 amp peak output current as a D.C. output current. The power supplies are ±15 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 capacitor in parallel with a 4.7 microfarad tantalum capacitor from each power supply pin to ground.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 curves to ensure high M.T.B.F. 1.) Find Power Dissipation PD=[(quiescent current) X (+VCC - (VCC))] + [(VS - VO) X IOUT] =(3.5 mA) X (30V) + (5V) X (0.1A) =0.1W + 0.5W =0.6W 2.) For conservative design, set TJ = +150°C. 3.) For this example, worst case TA = +25°C. 4.) RθJC = 85°C/W 5.) Rearrange governing equation to solve for RθSA: RθSA = (TJ - TA) / PD - (RθJC) - (RθCS) =(150°C - 25°C) / 0.6W - (85°C/W) - (0.15°C/W) =123°C/W TOTAL DOSE RADIATION TEST PERFORMANCE The heat sink in this example must have a thermal resistance of no more than 123°C/W to maintain a junction temperature of less than +150°C. This calculation assumes a case to sink thermal resistance of 0.15°C/W. Radiation performance curves for TID testing have been generated for all radiation testing performed by MSK. These curves show performance trends throughout the TID test process and can be located in the MSK0041RH radiation test report. The complete radiation test report will be available in the RAD HARD PRODUCTS section on the MSK website. http://www.mskennedy.com/store.asp?pid=9951&catid=19680 3 8548-65 Rev.
