Description AN896 APPLICATION NOTE A BATTERY CHARGER USING THE TSM101 by S. LAFFONT This technical note shows how to use the TSM101 integrated circuit with a switching mode power supply (SMPS) to realize a batte...
Features imitation is generally realized by sensing the current of the power transistor, in the primary side of the SMPS. The role of the TSM101 is to make a fine regulation of the output current of the SMPS and a precise voltage limitation. The primary current limitation is conserved and acts as a security for a fail-safe operation if a short-circuit occurs at the output of the charger. 2 - PRINCIPLE OF OPERATION The current regulation loop and the voltage limitation loop use an internal 1.24V band-gap voltage reference. This voltage reference has a good precision (better than 1.5%) and exhibits a ver...
