A driver can be configured to provide sensed phase currents as feedback to a controller to indicate the output currents from each phase of a switch mode power supply (SMPS). The driver can be configured to temperature compensate the sensed currents in one of two ways. If a temperature sensor is directly coupled to the driver, then the driver may be configured to temperature compensate the sensed currents from each phase based on a temperature measurement made by the temperature sensor. If a temperature sensor is not directly coupled to the driver, then the driver may be configured to temperature compensate the sensed current from each phase based on a temperature signal received from a bus coupled to the driver. The bus can communicate the temperature signal so that multiple drivers can utilize one temperature sensor.

In one embodiment, a bipolar cell () includes a cell boundary () that defines a cell active area (), a first array of bipolar transistors () is formed within the cell active area () and configured for a first function. The bipolar transistors () within the first array () are parallel to each other. The bipolar cell () further includes a second array of bipolar transistors () formed within the cell active area () and configured for a second function that is different than the first function. The bipolar transistors () within the second array () are parallel to each other and oriented in a different direction than the transistors () in the first array ().
