FREMONT, Calif., Feb. 10, 2015 /PRNewswire/ -- Exar Corporation (NYSE: EXAR), a leading supplier of high performance integrated circuits and system solutions, today introduced the XR77128, a universal PMIC which drives up to 4 independently controlled external DrMOS power stages at currents >40A for the latest 64-bit ARM processors, FPGAs, DSPs and ASICS. DrMOS technology is quickly growing in popularity in telecom and networking applications. These same applications find value in Exar's Programmable Power technology which allows low component count, rapid development, easy system integration, dynamic control and telemetry. Depending on output current requirements, each output can be independently configured to directly drive external MOSFETs or DrMOS power stages.
The XR77128 is quickly configured to power nearly any FPGA, SOC or DSP system through the use of Exar's design tool, PowerArchitectTM and programmed through an I2C based SMBus compliant serial interface. It can also monitor and dynamically control and configure the power system through the same I2C interface. Five configurable GPIOs allow for fast system integration for fault reporting and status or for sequencing control. A new Arduino-based development platform allows software engineers to begin code development for telemetry and dynamic control long before their hardware is available.
The XR77128 is available in a RoHS compliant, green/halogen free space-saving 7mm × 7mm TQFN and is priced at $7.75 in 1000-piece quantities. For more information, visit www.exar.com/xr77128.
