PMIC powers high current cores through DrMOS technology
A universal PMIC, which drives up to four independently controlled external DrMOS power stages at currents greater than 40A, has been released by Exar. Suitable for the latest 64-bit ARM processors, FPGAs, DSPs and ASICS, the XR77128 features the company’s programmable power technology, which allows for a low component count, rapid development, easy system integration, dynamic control and telemetry. To meet a wide range of output current requirements, each output can be independently configured to directly drive external MOSFETs or DrMOS power stages.
The device can configured using Exar’s design tool, PowerArchitect, and programmed through an I²C based SMBus compliant serial interface, which can also be used to monitor and dynamically control and configure the power system. Five configurable GPIOs allow for fast system integration for fault reporting and status or for sequencing control.
Housed in a 7×7mm TQFN package, the XR77128 is RoHS compliant and halogen free. The PMIC is available now, priced at $7.75 each and sold in 1000-piece quantities.
