Design flexibility is provided by the excellent device characteristics; 300 V Max offset and only 375 A (typical at 60V) of current consumption.

2 The LTC6101 operates on supplies from 4V to 60V and LTC6101HV operates on supplies from 5V to 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 wide operating supply range and high accuracy make the LTC6101 ideal for a large array of applications from automotive to industrial and power management.

3 A maxi-mum 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 LTC6101 is available in 5-lead SOT-23 and 8-lead MSOP Current Shunt Measurementn Battery Monitoringn Remote Sensingn Power Managementn Supply Range: 5V to 100V, 105V Absolute Maximum (LTC6101HV) 4V to 60V, 70V Absolute Maximum ( LTC6101 )n Low Offset Voltage: 300 V Maxn Fast Response: 1 s Response Time (0V to on a 5V Output Step)n Gain Configurable with 2 Resistorsn Low Input Bias Current: 170nA Maxn PSRR: 118dB Minn Output Current: 1mA Maxn Low Supply Current: 250 A, V S = 12Vn Specified Temperature Range.
