MIC5162

The MIC5162 is a dual regulator controller designed for high-speed bus termination. It offers a simple, low-cost JEDECcompliant solution for terminating high-speed, low-voltagedigital buses (i.e. DDR, DD2, DDR3, 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.

Designed to provide a universal solution for bus termination regardless of input voltage, output voltage, or load current, the desired MIC5162 output voltage can be programmed by forcing the reference voltage externally to desired voltage.

The MIC5162 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 operating junction temperature range of -40°C to +125°C.
