Voltage monitor checks under and over
Combined undervoltage and overvoltage monitor is filtered to reject brief glitches, thus ensuring reliable reset operation without false or noisy triggering.
Available now from Linear Technology, the LTC2912 is a combined undervoltage (UV) and overvoltage (OV) monitor for space-conscious applications Housed in a tiny 3 x 2mm DFN package, the voltage monitoring inputs of the LTC2912 include filtering to reject brief glitches, thus ensuring reliable reset operation without false or noisy triggering

Voltage monitors check automotive supplies
All devices have threshold accuracy of +/-1.5% over the automotive temperature range, allowing them to accurately monitor single channel point-of-load or multichannel applications.
Card power chip meets smart and SIM standards
The LTC4557 is a dual SIM/smart-card power supply and level translator, which provides both 1.8 and 3V SIM power and digital signal level shifting from a 3 x 3mm QFN package.
RF mixers take transformers onboard
Linear Technology has released two new high linearity up-converting RF active mixers with integrated RF transformers.
Programmed by external resistors, the UV and OV trip thresholds have a guaranteed +/-1.5% threshold accuracy of monitored voltages over temperature and give users the flexibility to tailor the IC to their specific voltage levels.
The LTC2912 features an adjustable timer to define the duration of the UV and OV reset outputs, which function independently of each other.
The IC is offered in three output configurations: the LTC2912-1 has a latch control for the OV output; the LTC2912-2 has an OV and UV output disable for margining applications; the LTC2913-3 is identical to the LTC2912-1 but provides a noninverting OV output.
The LTC2912 operates directly from 2.3 to 6V supplies, but an internal shunt regulator allows for operation with higher voltages such as 12, 24 and 48V, making it a perfect fit for systems with various voltage levels that also require reliable and accurate voltage monitoring, such as telecomms/network equipment, storage servers, desktop and notebook computers.
In addition to the single UV and OV monitor, dual and quad versions are also available.
The LTC2912 is offered in 8-lead ThinSOT and 3 x 2mm DFN packages and is specified over the commercial and industrial temperature ranges.
The LTC2912 is priced at US $1.45 each for 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
