Multifunction Timer
U2102B
Description
The monolithic integrated bipolar circuit U2102B is an
MOSFET or IGBT control circuit which allows
realization of an extremely wide range of timer and
dimmer functions. The integrated current monitoring
function additionally permits the power switch to be
reliably protected without an additional fuse.
