TPS3307-18M 三路处理器监控器
The TPS3307-18 is a micropower supply voltage supervisor designed for circuit initialization primarily in automotive DSP and processor-based systems, which require more than one supply voltage.
The TPS3307-18 is designed for monitoring three independent supply voltages: 3.3 V/1.8 V/adj,. The adjustable SENSE input allows the monitoring of any supply voltage >1.25 V.
The various supply voltage supervisors are designed to monitor the nominal supply voltage as shown in the following supply voltage monitoring table.
During power-on, RESET is asserted when the supply voltage VDD becomes higher than 1.1 V. Thereafter, the supply voltage supervisor monitors the SENSEn inputs and keeps RESET active as long as SENSEn remain below the threshold voltage VIT
