TPS3307-18 三路处理器监控电路

TPS3307-18 描述

The TPS3307 family is a series of micropower supply voltage supervisors designed for circuit initialization primarily in DSP and processor-based systems, which require more than one supply voltage. The product spectrum of the TPS3307-xx is designed for monitoring three independent supply voltages: 3.3V/1.8V/adj, 3.3V/2.5V/adj or 3.3V/5V/adj. The adjustable SENSE input allows the monitoring of any supply voltage >1.25V. The various supply voltage supervisors are designed to monitor the nominal supply voltage. During power-on, RESET is asserted when the supply voltage VDD becomes higher than 1.1V. Thereafter, the supply voltage supervisor monitors the SENSEn inputs and keeps RESET active as long as SENSEn remain below the threshold voltage VIT+.
