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.
