... The TSM102 integrated circuit includes two Oper- ational Amplifiers, two Comparators and one ad- justable precision Voltage Reference (2.5V to 36V, 0.4% or 1%). TSM102 can sustain up to 36V power supply volt- age. and C4. R15 polarizes the base of the transistor and at the same time limits the current through the zener diode during regulation mode of the auxilia- ry power supply ...

... TSM102/A Figure 2 : The Application Schematic - Battery Charger Secondary Side The first comparator ensures the “Low Battery” signal generation thanks to the comparison of a part of the charger’s output voltage (resistor bridge R17, R19) and the reference voltage. Prop- er hysteresis is given thanks to R20. An improve- ment to the chargers security and to the battery’ ...
