TPS3305-18DRG4

双处理器监事 DUAL PROCESSOR SUPERVISORS

DESCRIPON

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.
