General Description

The MIC5162 is a dual regulator controller designed for highspeed bus termination. It offers a simple, low-cost JEDEC compliant solution for terminating high-speed, low-voltage digital buses (i.e. DDR, SCSI, GTL, SSTL, HSTL, LV-TTL, Rambus, LV-PECL, LV-ECL, etc).

The MIC5162 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 sinked by the regulator.
