Summit Announces SMM151/2/3 Product Family of Environmental Monitoring Products

By pur, at Wednesday, August 20th, 2008, in Communication, Measurement, Instrumentation

The SMM151/2/3 family provides Digital Power Management via an I2C interface and non-volatile memory allowing the user to retrieve real-time parametric information (voltage/current) and configure power functions, such as: glitch filter duration for ignoring spurious noise signals, margin delay, margin high and low limits, GPIO power-up polarity, voltage monitoring mode (under-voltage or over-voltage) and device handling of fault conditions. The SMM151/2/3 family is supported by Summit's easy-to-use PC-based graphical (GUI) development environment that allows system designers to digitally program the output power supply, read current and voltage information and control a variety of power management functions with a few clicks of a mouse. In high-volume production Summit provides product that is pre-programmed with the customer's "custom configuration" at no extra cost..
