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.
