The LTM9100 μModule^® (micromodule) controller is a complete, galvanically isolated switch controller with I²C interface, for use as a load switch or hot swap controller. The load is soft started and controlled by an external N-channel MOSFET switch. Overcurrent protection minimizes MOSFET stress during start-up, input step and output short-circuit conditions. Owing to the isolated, floating character of the switch, it is easily configured for use in high side, low side and floating applications.

A single 5V supply powers both sides of the switch controller through an integrated, isolated DC/DC converter. A separate logic supply input allows easy interfacing with logic levels from 3V to 5.5V, independent of the main supply. Isolated measurements of load current and two additional voltage inputs are made by a 10-bit ADC, and accessed via the I²C interface.

The logic and I²C interface is separated from the switch controller by a 5kV_RMS isolation barrier, making the LTM9100 ideal for systems where the switch operates on buses up to 1000V_DC, as well as for providing galvanic isolation in systems where a ground path is broken to allow large common mode voltage swings. Uninterrupted communication is guaranteed for common mode transients of up to 30kV/μs.

Product Details

Demonstration circuit 2423A showcases the LTM9100 Isolated Switch Controller in either a typical 48V application (–A) or in a high voltage 380V application (–B). The board may be configured for either high side or low side operation, dependent on the connection of external supply and load to the banana jacks. An on board capacitive load may also be wired into the circuit. LEDs indicate the presence of input and output voltage.
