TPS3307-33D

产品概述

The TPS3307-33D is a triple-processor Supervisory Circuit with active-low push-pull output. The MicroPower supply voltage supervisor designed for circuit initialization primarily in DSP and processor-based systems, which require more than one supply voltage. 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+. An internal timer delays the return of the /RESET output to the inactive state (high) to ensure proper system reset. The delay time, td (typ)=200ms, starts after all SENSEn inputs have risen above the threshold voltage VIT+.
