APPLICA TION NOTER. LIOU Li-Ion BATTERY CHARGER USING TSM102A
This application note explains howto use the
TSM102in an SMPS-type battery charger which
features:. Voltage Control. Current Control. Low Battery Detection and EndOf Charge
Detection- TSM102 PRESENTATION
The TSM102 integratedcircuitincludes two Opera-
tional Amplifiers, two Comparators and one adjust-
able precision Voltage Reference (2.5Vto 36V,
0.4%or 1%).

Figure1: TSM102 Pinout- APPLICATION CONTEXT AND PRINCIPLE OPERATION the battery charging field which requires ever
increasing performancesin more and more re-
duced space, the TSM102Aprovidesan attractive
solutionin termsof PCB area saving, precision and
versatility.
Figure2 shows the secondary sideofa battery
charger (SMPS type) where TSM102Ais usedin
optimised conditions: the two Operational Amplifi-
ers perform current and voltage control, the two
Comparators provide ”Endof Charge” and ”Low
Battery” signals and the Voltage Reference en-
sures precise referenceforall measurements.
The TSM102Ais suppliedby an auxiliary power
supply (forward configuration- D7) regulatedbya
bipolar transistor anda zenerdiodeonits base (Q2
and DZ), and smoothedby the capacitors C3 and
C4. R15 polarizes the baseof the transistor andat
the same time limits the current through the zener
diodeduring regulationmode ofthe auxiliary power
supply.
The current and voltage regulations are made
thanksto the two OperationalAmplifiers.
The first amplifier senses the current flow through
the sense resistor Rs and comparesit witha part the reference voltage (resistor bridge R7, R8,
R9). The second amplifier compares the reference
voltage witha part ofthe charger’s output (resistor
bridge R1, R2, R3).
When eitherof these two operational amplifiers
tendsto lowerits ouput, this linear informationis
propagatedtowards theprimaryside viatwo ORing
diodes (D1, D2) and an optocoupler (D3). The
compensation loopsof these regulation functions
are ensuredby the capacitorsC1 and C2.
