The LTC6101/LTC6101HV are versatile, high voltage, high side current sense amplifiers. Design flexibility is provided by the excellent device characteristics; 300?V Max offset and only 375?A (typical at 60V) of current consumption. The LTC6101 operates on supplies from 4V to 60V and LTC6101HV operates on supplies from 5V to 100V.The LTC6101 monitors current via the voltage across an external sense resistor (shunt resistor). Internal circuitry converts input voltage to output current, allowing for a small sense signal on a high common mode voltage to be translated into a ground referenced signal. Low DC offset allows the use of a small shunt resistor and large gain-setting resistors. As a result, power loss in the shunt is reduced.The wide operating supply range and high accuracy make the LTC6101 ideal for a large array of applications from automotive to industrial and power management. A maximum input sense voltage of 500mV allows a wide range of currents to be monitored. The fast response makes the LTC6101 the perfect choice for load current warnings and shutoff protection control. With very low supply current, the LTC6101 is suitable for power sensitive applications.The LTC6101 is available in 5-lead SOT-23 and 8-lead MSOP packages.Applications Current Shunt Measurement Battery Monitoring Remote Sensing Power Management

The LTC3562 is a quad high efficiency monolithic synchronous step-down regulator with an I2C interface. Two regulators are externally adjustable and can have their feedback voltages programmed between 425mV and 800mV in 25mV steps (Type A). The other two regulators are fixed output regulators whose output voltages can be programmed between 600mV and 3.775V in 25mV steps (Type B). All four regulators operate independently and can be put into pulse skip, LDO, Burst Mode operation, or forced Burst Mode operation through I2C control. The Type-A regulators have separate RUN pins that can be enabled if I2C control is unavailable. The 2.85V to 5.5V input voltage range makes the LTC3562 ideally suited for single Li-Ion battery-powered applications. At low output load conditions, the regulators can be switched into LDO, Burst Mode operation, or forced Burst Mode operation, extending battery life in portable systems. The quiescent current drops to under 100uA with all regulators in LDO mode, and under 0.1uA when all regulators are shut down.Switching frequency is internally set to 2.25MHz, allowing the use of small surface mount inductors and capacitors. All regulators are internally compensated. The LTC3562 is available in a low profile 3mm x 3mm QFN package.Applications Miscellaneous Handheld Applications with Multiple Supply Rails Personal Information Appliances Wireless and DSL Modems Digital Still Cameras MP3 Players Portable Instruments
