LTC6101CIS5#TRPBF

The LTC6101CIS5#TRPBF from Analog Devices is a versatile, high voltage, high-side current sense amplifier housed in a low-profile SOT-23 package. It is designed to monitor current by measuring the voltage across an external sense resistor. The device operates on supply voltages ranging from 4V to 60V for the LTC6101 and 5V to 100V for the LTC6101HV variant. Key features include a maximum offset voltage of 300µV, a fast response time of 1µs, and low current consumption. The internal circuitry converts the input sense voltage to an output current, enabling a ground-referenced signal output from a high common-mode voltage.

This amplifier is suitable for applications requiring precise current shunt measurement, such as in automotive, industrial, and power management systems. The low offset voltage allows for the use of small shunt resistors and large gain-setting resistors, which reduces power loss. A maximum input sense voltage of 500mV supports monitoring a wide range of currents. The SOT-23 package is suitable for space-constrained designs.

Applications include current shunt measurement and battery monitoring. The device's characteristics make it ideal for various power management tasks where accurate current sensing is critical.
