The LTC2053 output capability limits this basic configuration to low current applications. There is always a transition halfway between the conditioned transitions. The maximum battery current is assumed to be 500mA due to the 50mV full-scale sense voltage requirement of the LTC4150. A digital modulation technique that allows data transmission by changing the frequency of the carrier wave according to the digital modulating signal is known as frequency shift keying (FSK). The current sense output is resistor divided down so that one comparator will trip at an early warning level and the second at a danger level of current to the load (100mA and 250mA in this example). A unique benefit of this configuration is that when the LT6100 is powered down, its battery sense inputs remain high impedance, drawing less than 1A of current. An OFDM carrier signal is the sum of a number of orthogonal subcarriers, with baseband data on each subcarrier being independently modulated commonly using some type of quadrature amplitude modulation (QAM) or phase-shift keying (PSK).
