Dual operational amplifier and 2.5 V shunt regulator  
SA58605  
APPLICATION INFORMATION  
The SA58605 may be used for various voltage control applications  
in which the input threshold voltage exceed 2.5 V for Amp “A” and  
154 mV for Amp “B”. When either or both input threshold voltage is  
SA58605 follows and drops below 2.5 V. This causes the output  
(pin 1) to go HIGH and the LED is turned off. Q1 base drive is  
reduced and Q2 is increased. Thus, the PW modulation is  
increased, and B+ is able to satisfy the load requirements of the  
battery and circuitry. As B+ is increased above 5 V, it causes the  
input to Amp “A” to increase above 2.5 V. Then, the output goes  
LOW and the LED is activated which turns on the detection diode.  
This increases the drive on Q1 and pulls down the base of Q2  
reducing it base drive. With Q2 conducting less, the PW modulation  
is decreased and B+ is reduced. Under quasi-steady state, B+ is  
maintained at 5 V.  
exceeded the output is pulled LOW. The output is connected to V  
with a pull-up resistance.  
CC  
Figure 7 shows the schematic for a Universal Converter/Charger  
circuit in which the SA58605 Amp “A” is used to monitor the B+ level  
of the converter/charger. Amp “B” input is pulled to ground through a  
390 resistor and will remain there. The input to the Amp “A” is  
maintained at 0.5 × B+ with the voltage divider of the two 1.5 kΩ  
resistors. As B+ drops below 5 V, the input to Amp “A” of the
