TPS3707-30 具有电源故障检测功能的处理器监控电路

TPS3707-30 描述

The TPS3705, TPS3707 family of microprocessor supply-voltage supervisors provide circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power-on, RESET\ is asserted when the supply voltage VDD becomes higher than 1.1 V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET\ active as long as VDD remains below the threshold voltage VIT+. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. The delay time, tdtyp = 200 ms, starts after VDD has risen above the threshold voltage VIT+. When the supply voltage drops below the threshold voltage VIT–, the output becomes active (low) again. No external components are required.
