• Manufacturer Part Number: TSM105
• Description: Constant Voltage and Constant Current Controller
• Manufacturer: ST Microelectronics

MACROMODEL
The model is centred at a typical supply voltage of 5 V
and at an ambient temperature of 70°C (the typical tem-
perature within a battery pack).
To obtain the right values for amplifier gain, it is RECOM-
MENDED TO SET THE SIMULATION TEMPERATURE
TO 70°C.
SUPPLY CURRENT: 1.15 mA
VOLTAGE REFERENCE: 1.210 V
AMPLIFIER CHARACTERISTICS:
TCA (Amplifier for voltage control)
Gain: gm = 3.6 mA/mV
1st dominant pole: 1E5 Hz
UGBW: 8E6 Hz
TCAFC (Amplifier for current control)
Gain: gm = 8.1 mA/mV
1st dominant pole: 1E5 Hz
UGBW: 2E7 Hz
