INTEGRATED CIRCUITS SA58605 Dual operational amplifier and 2.
Philips Semiconductors Product data Dual operational amplifier and 2.5 V shunt regulator DESCRIPTION The SA58605 incorporates two op amps and 2.5 V shunt regulator in an unique circuit configuration. The output of the device is inverted when the inverting inputs of either or both op amps exceed the internally set reference voltages at their non-inverting inputs. Amp “A” is referenced to 2.5 V while Amp “B” is referenced to 154 mV.

Philips Semiconductors Product data Dual operational amplifier and 2.5 V shunt regulator SA58605 APPLICATION INFORMATION 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.
