摘要:
A low-side (LS) output pre-driver (10) has a short-circuit-to-battery fault detection scheme for a MOSFET switch (12) having a drain connection to a load connected to a battery voltage and a source connection tied to ground. The LS output pre-driver includes a comparator (16), a reference voltage selector (22), a multi-phase blank/filter (18), a multi-phase control timer (24). The first signal of the multi-phase control timer instructs the reference voltage selector to select which of the plurality of reference voltage signals is provided to the second input of the comparator. The second signal of the multi-phase control timer instructs the multi-phase blank/filter to change from one of the plurality of time intervals to another of the plurality of time intervals.

Interconnection meter socket adapters are provided. An interconnection meter socket adapter comprises a housing enclosing a set of electrical connections. The interconnection meter socket adapter may be configured to be coupled to a standard distribution panel and a standard electric meter, thereby establishing connections between a distribution panel and a user such that electrical power may be delivered to the user while an electrical meter measures the power consumption of the user. A power regulation module is disposed between the interconnection meter socket adapter, and configured to selectively connect one or more energy sources or energy sinks.
摘要:
A circuit comprises a battery field-effect transistor (FET) coupled between a battery and an electronic system so that current from the battery flows through the battery FET to the electronic system. A replica FET couples the battery to a current sensing circuit. One of the battery FET and the replica FET comprises a plurality of parallel FET segments having separate control terminals. A logic block provides a plurality of switch control signals based on a system state input. A switching circuit receives the switch control signals and selectively couples the separate control terminals of the FET segments to one of a first reference voltage terminal or a second reference voltage terminal to independently turn each FET segment on or off. The current sensing circuit provides a voltage indicative of the current flowing through the replica FET.
