1 / 15 page  TSM101/A VOLTAGE AND CURRENT CONTROLLER June 1999 1 2 3 4 8 5 6 7 Vref PIN CONNECTIONS ® . 1.24V SERIES VOLTAGE REFERENCE WITH 10mA OUTPUT CURRENT AND 1% PRECI- SION (TSM101A) . TWO OPERATIONAL AMPLIFIERS WITH ORED OUTPUT AND 1MHZ GAIN BAND- WIDTH PRODUCT . BUILT-IN CURRENT GENERATOR WITH EN- ABLE/DISABLE FUNCTION . 4.5 TO 32V SUPPLY VOLTAGE RANGE . SO8, DIP8 AND TSSOP8 PACKAGES DESCRIPTION The TSM101/TSM101Aintegrated circuit incorpo- rates a high stability series band gap voltage refer- ence, two ORed operational amplifiers and a current source. This IC compares the DC voltage and the current level at the output of a switching power supply to an internal reference. It provides a feedback through an optocoupler to the PWM controller IC in the primary side. The controlled current generator can be used to modify the level of current limitation by offsetting the information coming from the current sensing resistor. APPLICATIONS This circuit is designed to be used in battery charg- ers with a constant voltage and a limited output current. It can be used in every types of applicationrequiring a precision voltage regulation and current limita- tion. Other applications include voltage supervisors, over voltage protection...
