Semiconductors Provide Real-time Power Information

Fri, 09/19/2008 - 7:42am

LISTED UNDER:

Summit SMM151/2/3Using integrated 10-bit A/D conversion, Summit Microelectronics’ SMM151/2/3 environmental monitoring semiconductors allow systems to obtain real-time input current and differential output voltage information, and adjust operating modes. The SMM151 and SMM152 offer output voltage margining from 0.3 V to VDD (up to 5 V), 1% accuracy and margining during development or production. The SMM152 and SMM153 integrate 4 general-purpose inputs and outputs and 2 logic outputs. The RoHS-compliant devices utilize a I2C interface and non-volatile memory for power functions including glitch filter duration, margin delay, margin high and low limits, GPIO power-up polarity, voltage monitoring mode and device handling of fault conditions. The 5 mm² 28-pad QFN-packaged semiconductors uses a PC-based GUI environment for support in applications including such as computing servers, wireless and wireline routers, switches, storage servers and telecom equipment. The Pb-free components operate from a 2.7 V to 5.5 V input, accept voltages from 4 V to 15 V, and have a temperature range from 0°C to 70°C or -40°C to 85°C. Pricing is $3.49 (SMM151), $3.79 (SMM152) and $2.79 (SMM153) in 1,000 quantities.
