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.

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 Ω 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
