Toaster Controller
BCT5511 Toaster Controller
General
BCT5511 is designed for toaster applications. It
is basically a timer, setting by external RC
components, to stop heating of toaster. Besides
normal timer, it also has defrost and reheat
functions. It is built in oscillation detecting
circuitry. If the oscillation of the IC is not working,
the toaster will not start working. It also has the
function of timing protection, If the IC is switched
on over 300s, The IC will stop the heating for
safety. It provides low cost solution for toaster.
