24V SERIES VOLTAGE REFERENCE WITH 10mA OUTPUT CURRENT AND 1% PRECISION (TSM101A) TWO OPERATIONAL AMPLIFIERS WITH ORED OUTPUT AND 1MHZ GAIN BANDWIDTH PRODUCT BUILT-IN CURRENT GENERATOR WITH ENABLE/DISABLE FUNCTION 4.
5 TO 32V SUPPLY VOLTAGE RANGE SO8, DIP8 AND TSSOP8 PACKAGES N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) P TSSOP8 (Thin Shrink Small Outline Package) ORDER CODES DESCRIPTION The TSM101/TSM101Aintegrated circuit incorporates a high stability series band gap voltage reference, 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 chargers with a constant voltage and a limited output current.
It can be used in every types of applicationrequiring a precision voltage regulation and current limitation.
Other applications include voltage supervisors, over voltage protection.
