description
The TPS3306 family is a series of supervisory
circuits designed for circuit initialization, which
require two supply voltages, primarily in DSP and
processor-based systems.
The product spectrum of the TPS3306-xx is
designed for monitoring two independent supply
voltages of 3.3 V/1.5 V, 3.3 V/1.8 V, 3.3 V/2 V, 3.3
V/2.5 V, or 3.3 V/5 V.
