A monitoring device has an event monitor, an uplink interface to a chain controller device, and a downlink interface to a further monitoring device, and a daisy controller for coupling the uplink to the chain downlink. The event monitor, in response to detecting an event in sleep mode, generates a wake-up signal. The daisy controller sets the electronic monitoring device to a wake-up request mode and disables the bidirectional data communication via the downlink interface, and subsequently transmits a wake-up request to the chain controller device via the uplink interface. In response to receiving a wake-up command, the daisy controller re-enables the bidirectional data communication via the downlink interface and sets the electronic monitoring device to the operational mode. Thereby a wake-up sequence is performed while the wake-up request mode avoids bus conflicts.

Embodiments of an electronic circuit for monitoring a battery stack enable cell balancing while conserving pin-count of the circuit package. The illustrative electronic circuit comprises a battery monitoring integrated circuit configured for monitoring a plurality of cells in the battery stack. The battery monitoring integrated circuit is arranged to share a common node pin between two adjacent battery cells in the battery stack for the purpose of cell balancing.

Cell balance configuration for pin count reduction

Geometrically based system and method for receiving capacitive sensory input. User input may be received by a capacitive sensing pad. A signal may be generated by the capacitive sensing pad. The signal may indicate a size of an area in which the user input is received. The signal may be received by an input composed in processing circuitry and coupled to the capacitive sensing pad. A location of the user input may be determined by the processing circuitry based on the signal.
