ent through the current sense resistor R1. The constant current feedback loop operates as follows. Initially, the emitter and collector current of Q2 are both approximately 1 mA, thus providing gate drive to the MOSFET Q3, turning it on. The output of the LM301A op-amp is low. As Q3's current reaches 1A, the voltage across R1 approaches 50 mV, thus canceling the 50 mV drop across R2, and causing the op-amp's output to start going positive, and begin sourcing current into R8. As more current is forced into R8 from the op-amp, the collector current of Q2 is reduced by the same amount, which decreases the gate drive to Q3, to maintain a constant 50 mV across the 0.05 current sensing resistor, thus maintaining a constant 1A of charge current. The current limit loop is stabilized by compensating the LM301A with C1 (the standard frequency compensation used with this op-amp) and C2, which is additional compensation needed when D3 is forward biased. This helps speed up the response time duri

LM301A Operational Amplifiers General Description The LM101A series are general purpose operational amplifiers which feature improved performance over industry standards like the LM709. Advanced processing techniques make possible an order of magnitude reduction in input currents, and a redesign of the biasing circuitry reduces the temperature drift of input current. Improved specifications include: * Offset voltage 3 mV maximum over temperature (LM101A/LM201A) * Input current 100 nA maximum over temperature (LM101A/LM201A) * Offset current 20 nA maximum over temperature (LM101A/LM201A) * * Guaranteed drift characteristics * Slew rate of 10V/s as a summing amplifier This amplifier offers many features which make its application nearly foolproof: overload protection on the input Offsets guaranteed over entire common mode and supply voltage ranges Fast AC/DC Converter and output, no latch-up when the common mode range is exceeded, and freedom from oscillations and compensation with a single 30 pF c
