Multi-mode power train integrated circuit

A configurable driver integrated circuit, comprising:

• circuitry operating in a fixed power supply domain;
• a plurality of input/output terminals for interfacing exterior of the integrated circuit and including power supply input terminals interfacing with the fixed power supply domain;
• a plurality of isolated driver circuits, each driver circuit including:
• a pair of transistors, each having a source and a drain, and each of the source and drain thereof connected to a dedicated and respective one of the input/output terminals,
• gate driver circuitry operating in a floating power supply domain relative to the fixed power supply domain for driving a gate of each of the transistors, and
• level shift circuitry for shifting the level of an input logic signal from the fixed voltage domain to the floating power supply domain for input to the gate driver in the associated floating voltage domain;
• and
• the circuitry operating in the fixed voltage power supply domain including logic circuitry for generating logic signals in the fixed voltage domain for driving the inputs of the level shift circuit in each of the driver circuits and controlling the operation of each of the driver circuits in accordance with a predetermined configuration defined by external circuit components configuring the driver circuits in a predefined driver class to drive a load.
