A power management integrated circuit includes pairs of high-side and low-side drivers, sensing circuitry, and a processor. The high-side and low-side drivers are used in combination with external discrete NFETs to drive multiple windings of a motor. The N-channel LDMOS transistor of each high-side driver has an associated isolation structure and a tracking and clamping circuit. If the voltage on a terminal of the integrated circuit pulses negative during a switching of current flow to the motor, then the isolation structure and tracking and clamping circuit clamps the voltage on the isolation structure and blocks current flow from the substrate to the drain. An associated ESD protection circuit allows the voltage on the terminal to pulse negative. As a result, a large surge of current that would otherwise flow through the high-side driver is blocked, and is conducted outside the integrated circuit through a body diode of an external NFET.

Disclosed are methodology and corresponding apparatus subject matters for providing improved efficiency in the collection of data from a large number of metrology devices associated with an Automated Meter reading (AMR) network. AMR network operation produces randomly spaced transmissions from individual nodes in the network. When an AMR system wishes to retrieve data from a large number of points over an AMR network, a broadcast or multicast request is transmitted to appropriate nodes. A time window is defined either in such request or in the devices themselves such that start and end offsets from the time of the request are received by the node. The start offset provides a quiet period to insure request delivery to all the appropriate nodes. The end offset provides a time by which the requested data must be returned. Responses are sent randomly within the window established by the start and stop offset times.
