Access to an internal signal node (Pin 3) provides an option to include a filtering function with one added capacitor. The input leads become very Hi-Z when V CC is powered down, so as not to drain batteries for example. The A2 and A4 pins can be strapped various ways to provide a wide range of internally fixed gains. The monitored supply can range anywhere from V CC + 1.4V up to 48V. The internal circuitry, including an output buffer, typically operates from a low voltage supply, such as the 3V shown. This is the basic LT6100 circuit configuration. With these circuits the total current supplied to a load is monitored in the positive power supply line. This chapter discusses solutions for high side current sensing.
