PA51 PADSIA APEX MiCROTECHNOLOGY CORPORATION FEATURES WIDE SUPPLY RANGE +10 to +40V HIGH OUTPUT CURRENT +10A Peak SECOND SOURCEABLE OPA501, 8785 CLASS C OUTPUT Low Cost LOW QUIESCENT CURRENT ~ 2.6mA APPLICATIONS DC SERVO AMPLIFIER MOTOR/SYNCHRO DRIVER * VALVE AND ACTUATOR CONTROL e DC OR AC POWER REGULATOR DESCRIPTION The PA51 and PA51A are high voltage, high output current operational amplifiers designed to drive resistive, inductive and capacitive loads. Their complementary common emitter output stage is protected against transient inductive kickback and optimized far low frequency applications where crossover distortion is not critical. These amplifiers are not recom- mended for audio, transducer or deflection coil drive circuits. The safe operating area (SOA) is fully specified and can be observed for all operating conditions by selection of user programmable current limiting resistors. Both amplifiers are internally compensated for all gain settings. For continuous operation under load. mounting on a heatsink of proper rating is recommended. Do not use isolation washers! This hybrid integrated circuit utilizes thick film conductors, ceramic capacitors and semiconductor chips to maximize reliability, minimize size and give top performance. Ultrasoni- cally bonded aluminum wires provide reliable interconnec- tions at all operating temperatures. The 8-pin TO-3 package is electrically isolated and hermetically sealed. The use of com- pressible thermal washers and/or improper mounting torque will void the product warranty. Please see General Operating Considerations.

The sense resistor develops a feedback voltage proportional to motor current and the smalt signal properties of the Power Op Amp insure accuracy.

Derate internal power dissipation The power supply voltage specified under the TYP rating applies unless otherwise noted as a test condition. +V, and ~V, denote the positive and negative supply rail respectively. Total V, is measured from +V, to -V5. Rating applies if the output current alternates between both output transistors at a rate faster than 60Hz. Full temperature range specifications are guaranteed but not 100% tested. The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or subject to temperatures in excess of 850C to avoid generating toxic fumes. APEX MICROTECHNOLOGY CORPORATION * 5980 NORTH SHANNON RC'AD TUCSON.

Additional information can be found in the application notes. For information on the package outline, heatsinks, and mounting hardware, consult the Accessory and Package Mechanical Data section of the handbook. SAFE OPERATING AREA (SOA) The output stage of most power amplifiers has three distinct limitations: 1. The current handling capability of the transistor geometry and the wire bonds. 2. The second breakdown effect which occurs whenever the simultaneous collector current and collector-emitter voltage exceeds specified limits. 3. The junction temperature of the output transistors. = Oo yep oO AN aoo 8 8 o- an) D, S. @ a OUTPUT CURRENT FROM +V5 OR Vs (A) w to 5 7 10 15 20 30 40 50 70 80 SUPPLY TO OUTPUT DIFFERENTIAL VOLTAGE Vs Vo (V) The SOA curves combine the effect of of all limits for this Power Op Amp. For a given application, the direction and magnitude of the output current should be calculated or measured and checked against the SOA curves. Thisis simple for resistive loads but more complex for reactive and EMF generating loads. The following guidelines may save exten- sive analytical efforts. 1. Under transient conditions, capacitive and dynamic induc- tive loads up to the following maximums are safe: CAPACITIVE LOAD INDUCTIVE LOAD 4V, Lng= 5A y= t0A 1, = 5A |= 10A 40V 400pF 200uF 11mH 4.3mH 35V 800pF 400pF 20mH 5.0mH 30V 1,600uF 800pF 35mH 6.2mH 25V 5.0mF 2.5mF 50mH 15mH 20V 10mF 5.0mF 400mH 20mH 15V 20mF 10mF ia 100mH \f the inductive load is driven near steady state conditions, allowing the output voltage to drop more than 8V below the supply rail with Ly, = 10A or 15V below the supply rail with luw = 5A while the amplifier is current limiting, the inductor should be capacitively coupled or the current limit must be lowered to meet SOA criteria. ** Second breakdown effect imposes no limitation but thermal limitations must still be observed. 2. The amplifier can handle any EMF generating or reactive load and short circuits to the supply rail or shorts to common if the current limits are set as follows at T, = 85C. SHORT TO +V, SHORT TO tv, C, L, OR EMF LOAD COMMON 45V OA 1.3A 40v 0.2A 1.54 35V 0.3A 1.6A 30V 0.54 2.0A 25V 1.2A 2.4A 20V 1.5A 3.0A 15V 2.0A 4.0A These simplified limits may be exceeded with further analysis using the operating conditions for a specific application. 3. The output stage is protected against transient flyback. However, for protection against sustained, high energy flyback, external fast-recovery diodes should be used. CURRENT LIMIT Proper operation requires the use of two current limit resis- tors, connected as shown in the external connection diagram. The minimum value for Re, is .06 ohm, however for optimum reliability it should be set as high as possible. Refer to the General Operating Considerations" section of the handbook for current limit adjust details. PasiUi REV.
