The present application relates to a circuit of a frequency divider arranged to divide a frequency of an input clock signal by odd integer N and a method of operating the circuit. A shift register comprises a number of N+1 clock gating cells, which are connected in series to each other, and a shift logic. An input clock signal is fed into clock signal inputs of each one of the number of N+1 clock gating cells. The shift logic is configured to receive enable signals from a set of the number of N+1 clock gating cells and to generate a feedback signal, which is supplied to a gate enable input of the first one of the number of N+1 clock gating cells. A multiplexer is configured to receive at input ports N+1 gated clock signals and to output a rotation clock signal, which has a frequency of 2/N of the frequency of the input clock signal. A frequency generator is configured to receive the rotation clock signal and to generate an output clock signal having a frequency of 1/N.

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.

The present invention pertains to a linear power regulator device, comprising an internal pass device, a driver device having a driver output arranged to drive the internal pass device via the driver output, wherein the linear power regulator device comprises an external connection connectable or connected to an external pass device; and wherein the driver device is arranged to drive an external pass device via the driver output and the external connection. The invention also pertains to a corresponding electronic device.

An apparatus for sensing current of a vehicle battery employs an extended counting analog-to-digital conversion process () to a chopped and amplified voltage appearing across a low ohmic shunt resistor () placed between the negative pole of the vehicle's battery and the chassis ground of the vehicle. Gain adjustment control of a programmable gain amplifier () by matching the gain to the dynamic range of the ADC () permits a high dynamic signal sensing.
