LTC6101/LTC6101HV High Voltage, High-Side Current Sense Amplifier in SOT-23 FEATURES DESCRIPTION n Supply Range: The LTC 6101/LTC6101HV are versatile, high voltage, high 5V to 100V, 105V Absolute Maximum (LTC6101HV) side current sense amplifiers. Design flexibility is provided 4V to 60V, 70V Absolute Maximum (LTC6101) by the excellent device characteristics 300V Max offset n Low Offset Voltage: 300V Max and only 375A (typical at 60V) of current consumption. n Fast Response: 1s Response Time (0V to 2.5V on The LTC6101 operates on supplies from 4V to 60V and a 5V Output Step) LTC6101HV operates on supplies from 5V to 100V. n Gain Configurable with 2 Resistors The LTC6101 monitors current via the voltage across an n Low Input Bias Current: 170nA Max external sense resistor (shunt resistor). Internal circuitry n PSRR: 118dB Min converts input voltage to output current, allowing for a n Output Current: 1mA Max small sense signal on a high common mode voltage to n Low Supply Current: 250A, V = 12V S be translated into a ground referenced signal. Low DC n Specified Temperature Range: 40C to 125C offset allows the use of a small shunt resistor and large n Operating Temperature Range: 55C to 125C gain-setting resistors. As a result, power loss in the shunt n Package Option for High Voltage Spacing is reduced. n Low Profile (1mm) SOT-23 (ThinSOT) Package The wide operating supply range and high accuracy make the LTC6101 ideal for a large array of applications from APPLICATIONS automotive to industrial and power management. A maxi- mum input sense voltage of 500mV allows a wide range n Current Shunt Measurement of currents to be monitored. The fast response makes the n Battery Monitoring LTC6101 the perfect choice for load current warnings and n Remote Sensing shutoff protection control. With very low supply current, n Power Management the LTC6101 is suitable for power sensitive applications. All registered trademarks and trademarks are the property of their respective owners. The LTC6101 is available in 5-lead SOT-23 and 8-lead MSOP packages.
