DESCRIPTION
The TSM115 integrated circuit incorporates all
sensing circuitry to protect from over and under
voltage and over current a multiple output power
supply (3.3V, +5V and ±12V).
TSM115 incorporates all the necessary functions
for Housekeeping features which allow safe
operation in all conditions, and very high system
integration.
