General Description

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, lowvoltage 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.
