Transient Immune Undervoltage Sensing Circuit

The LX7001 is an improved undervoltage sensing circuit specifi- cally designed for use as a reset controller in microprocessor-based systems. Today's complex miniaturized systems present difficult challanges to the system designer such as overcom- ing spurious noise problems. The LX7001 is optimized for systems that must be tolerant of high-speed power supply glitches caused by high-speed Logic transitions and similar switching phenomena. The LX7001 offers a unique stage that couples glitch immunity with a micropower, ultra- stable band-gap reference for preci- sion sensing of undervoltage condi- tions. It offers the designer an economical, space-efficient solution for low supply voltage detection when used in combination with a single pull-up resistor. Adding one capacitor offers the functionality of a programmable delay time after power returns. Additionally, the LX7001 offers excellent temperature stability. A high-quality trimmed voltage reference and bias circuit permit very accurate and repeatable undervoltage sensing. The remaining blocks consist of a Comparator with hyster- esis, high current clamping Diode and Open Collector output stage capable of sinking up to 60mA. The LX7001 's RESET output is specified to be fully functional at VIN=1V. By Microsemi Corporation
