TPS3305 DUAL PROCESSOR SUPERVISORS

The TPS3305 family is a series of micropower supply voltage supervisors designed for circuit initialization. Its dual monitor topology is well-suited to use in DSP and processor-based systems, which often require two supply voltages, core and I/O. RESET is asserted when the voltage at either SENSEn pin falls below its threshold voltage, VIT. When both SENSEn.
