Sunnyvale, CA Maxim introduces the MAX16010-MAX16014 overvoltage protection circuits designed for systems with high transient voltages as found in automotive, industrial, and telecommunication applications. The devices operate from 5.5 V to 72 V, and can be configured to provide overvoltage, undervoltage, or window monitoring while consuming only 20 µA of quiescent current. Both circuits have two independent comparators for monitoring both overvoltage and undervoltage conditions. The MAX16010 provides complementary enable inputs, while the MAX16011 offers an active-high enable input and a logic input to invert one of the two outputs. Offering greater design flexibility, the MAX16012 has a comparator providing access to both inverting and noninverting inputs, along with a reference output. The device can be configured to monitor either overvoltage or undervoltage conditions. Both circuits are capable of driving two external p-channel MOSFETs to prevent reverse battery and overvoltage conditions. The MAX16014 also features a latch-off feature to keep the load disconnected until the power is recycled. All devices are offered in a small, 3 x 3mm TDFN package and are fully specified from -40 °C to +125 °C. Prices start at $1.08 (1000-up, FOB USA).

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
