Device Overview

Summary

The MIC5164 is a dual regulator controller designed for high speed bus termination. It offers a simple, low-cost JEDEC-compliant solution for terminating high-speed, low-voltage digital buses (i.e. DDR, DDR2, DDR3, SCSI, GTL, SSTL, HSTL, LV-TTL, Rambus, LV-PECL, LV-ECL, etc) with a Power Good (PG) signal. The MIC5164 controls two external N-Channel MOSFETs to form two separate regulators. It operates by switching between either the high-side MOSFET or the low-side MOSFET depending on whether the current is being sourced to the load or sunk by the regulator. Designed to provide a universal solution for bus termination regardless of input voltage, output voltage, or load current, the desired MIC5164 output voltage can be programmed by forcing the reference voltage externally to the desired voltage. The MIC5164 operates from an input of 1.35V to 6V, with a second bias supply input required for operation. It is available in the tiny MSOP-10 package with an operating junction temperature range of - 40°C to + 125°C.
