... 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 ...
