description

LTC^®The 6102/LTC6102HV are general-purpose, high voltage, high side current sense amplifiers. The high supply voltage ratings of these devices allow them to be used in many high-side applications, while low drift and offset ensure accuracy over a wide range of operating conditions. The LTC6102-1 is a version of the LTC6102 that includes a low power shutdown mode to save the system in standby mode.

The LTC6102/LTC6102HV monitor current through a voltage across an external sense resistor (shunt resistor). Internal circuitry converts the input voltage to output current, allowing a small sense signal on a large common-mode voltage to be converted to a signal with ground as a reference potential. The low DC offset allows the use of very low shunt resistor values and large gain setting resistors. As a result, the power consumption in the tap is reduced.

The wide operating supply range and high accuracy make the LTC6102 ideal for a wide range of applications, from automotive to industrial and power management. The maximum input sense voltage of 2V enables it to monitor a wide range of currents and voltages. The fast response makes the LTC6102 perfect for load current alarm and shutdown protection control.

All versions of the LTC6102 are available in 8-lead MSOP and 3mm × 3mm DFN packages.
