Status: In Production
The MIC5165 is a dual regulator controller designed specifically for low-voltage memory termination applications such as DDR3 and GDDR3/4/5. The MIC5165 offers a simple, low-cost JEDEC-compliant solution for terminating high-speed, low-voltage digital buses with a Power Good (PG) signal. The MIC5165 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 being sunk by the regulator. Designed to provide a universal solution for memory termination regardless of input voltage, output voltage, or load current, the desired MIC5165 output voltage can be programmed by forcing the reference voltage externally to the desired voltage. The MIC5165 operates from an input voltage as low as 0.75V up to 6V, with a second bias supply input required for operation. The MIC5165 is available in a tiny MSOP-10 package with an operating junction temperature range of -40°C to +125°C.
The MIC5165 eval board is used to demonstrate the MIC5165. The MIC5165 is a dual regulator controller for high-speed bus termination that 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) and features a Power Good output (PG) and an Enable input (EN).
