This pin pro- duces a voltage that is proportional to the voltage between VOUT and IOUT. IOUTMON will equal 1.2V when VOUT – IOUT = 58mV. This feature is generally useful only if a current sense resistor is applied between VOUT and IOUT. This is a high impedance output. Use a buffer to drive a load. IINMON (Pin L3): Input Current Monitor. This pin produces a voltage that is proportional to the voltage between IIN and VIN. IINMON will equal 1V when IIN – VIN = 50mV. This feature is generally useful only if a current sense resistor is applied between VIN and IIN. RUN(PinL4):LTM8055Enable.RaisetheRUNpinvoltage above 1.2V for normal operation. Above 1.2V (typical), but below 6V, the RUN pin input bias current is less than 1μA. Below 1.2V and above 0.3V, the RUN pin sinks 3μA so the user can define the hysteresis with the external resis- tor selection. This will also reset the soft-start function. If RUN is 0.3V or less, the LTM8055 is disabled and the SVIN quiescent current is below 1μA. IIN (Pin L9): Input Current Sense. Tie this pin to the input current sense resistor. The input average current sense threshold is 50mV, so the LTM8055 will regulate the input current to 50mV/RSENSE, where RSENSE is the value of the input current sense resistor in ohms. Tie to VIN when not used.Keepthispinwithin±0.5VofVINunderallconditions.
