DC2193A

DC2193A is a demonstration circuit that features the LT®6118, a high side current sense amplifier with a comparator and a 400mV reference. The demo board circuit amplifies the voltage across an on-board current sense resistor, to provide a precision unipolar voltage output that is proportional to the sensed current. The board has one on-board latching comparator and an integrated 400mV reference that sets the threshold for the comparator. The demonstration board includes circuitry to guarantee that the comparator resets on power up. The current sense gain and current fault limits are set by on board resistors. The gain is 2.5V/A and the comparator is set to trip at current threshold of 500mA.
