Description
The TSM114 integrated circuit incorporates all of
the sensing circuitry required to regulate and
protect a multiple-output power supply (3.3V, 5V,
and ±12V) from both over-voltage and
under-voltage.
The TSM114 also includes all of the necessary
functions for housekeeping features, which allow
for safe operation under all conditions, as well as
very high system integration.
A precise voltage reference is also integrated in
the TSM114
