DESCRIPTION
The DC2733 is a demonstration system for the
65V Dual Electronic Circuit Breaker with Current Monitors.
The LTC4249 provides dual independent 1.2A, 75mΩ
circuit breakers that can function independently or work
together in parallel. Each circuit breaker channel has its
own enable, ready, and IMON pins.
The DC2733 demo board gives access to both channels of
the LTC4249, including the independent RDY and IMON
outputs and the EN inputs. Resistors at the IMON pins set
the circuit breaker thresholds as well as the IMON current-
to-voltage gains. The IC draws power from the IN1 input.

RDY2 (LED1) Illuminates green when the RDY2 pin of the LTC4249 is high (active). On the DC2733A board there are two configuration jump- ers that connect the ENn inputs of the IC to the pushbutton V3.3 (LED3) Illuminates green when the V3.3 power rail is active (powered by IN1). - Page 4 DEMO MANUAL DC2733A QUICK START PROCEDURE It is also possible to use channels in parallel, as shown in Figure 2. Channels will share current, but remember that channel impedances are not perfectly matched, so cur- rents will share slightly unevenly. When the circuit breaker...
- Page 5 DEMO MANUAL DC2733A QUICK START PROCEDURE The IMON pin voltage represents the current flowing in use two switches in series, back-to-back, as shown in Figure 4. In this case the return current necessarily flows its channel. Attach a voltage meter or ADC to each IMON externally to the board, but the Kelvin GND connection is pin as shown in Figure 3.
