Abstract: In general, the disclosure describes circuits and techniques to operate power switch driver circuits as well as techniques to dynamically change configuration parameters. The power switch driver circuit of this disclosure may be configured to received communication signals along the same signal paths as for pulse modulated switching control signals. In other words, the power switch driver circuit may receive a main function signaling, switching the power switches on and off, overlaid with a secondary function signaling, communication, which may include configuration parameters. In this manner the power switch driver circuit may receive both switching (commutation) function and communication function along the same signal path.

Abstract: A battery cell circuit of a battery management system configured to receive, from a previous battery cell circuit of a plurality of battery cell circuits connected in a daisy chain configuration or ring configuration, an instruction requesting a value for the battery cell circuit and determine a comparison result value based on a comparison of the value for the battery cell circuit and a reference value. The battery cell circuit is further configured to output, to a controller, the comparison result value, wherein, to output the comparison result value, the battery cell circuit is configured to refrain from outputting the value for the battery cell circuit.

Abstract: A method includes applying a current to an input pin of an integrated circuit; converting an analog signal at the input pin to a digital stream using a Sigma-Delta modulator; converting the digital stream to a first digital output signal proportional to the analog signal in a first input range between a first analog signal value and a second analog signal value, where the first input range corresponds to a pre-determined range of the analog signal smaller than a full-scale input range of the analog signal; converting the digital stream to a second output signal; comparing the second output signal to a first threshold corresponding to a third analog signal value at the input pin that is outside of the first input range; and providing an indication of an open circuit condition at the input pin when the second output signal crosses the first threshold.

Abstract: A drive circuit includes an internal oscillator and a pre-drive controller coupled to the internal oscillator. The pre-drive controller can have a switch control output configured to be coupled to a switch input. The pre-drive controller can receive switch control data, receive a clock signal, receive a synchronization signal, synchronize the internal oscillator based on the clock signal and the synchronization signal, and generate a pulse modulated switching signal at the switch control output based on the switch control data and the internal oscillator.
