TPS3305中文资料具有看门狗计时器的双处理器电压监控器数据手册TI规格书

描述 Description

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 pins are again above their respective threshold voltages, RESET is held low for the factory-programmed delay time (200ms typ). RESET is also asserted if the watchdog input (WDI) is not toggled for more than 1.6s typ.The TPS3305-xx devices are available in either 8-pin MSOP or SO packages, and are specified for operation over a temperature range of -40°C to +85°C.
