The TPS3305 family is a series of micropower supply voltage supervisors designed for circuit initialization, primarily in DSP and processor-based systems, which require two supply voltages. The product spectrum of the TPS3305 is designed for monitoring two independent supply voltages of 3.3 V/1.8 V, 3.3 V/2.5 V or 3.3 V /5 V.
