  • 使用H橋變壓器驅動器,充電超級電容器

    Abstract: With its small size and large load (10W) capability, the MAX13256 H-bridge transformer driver is an attractive solution forcharging supercapacitors (supercaps). However, a large capacitance on the output of the circuit can force the driver into fault modeat startup, due to the high initial charge current. This application note presents a solution that allows users to charge a largecapacitance without going into fault.

  • G3-PLC技術使電動汽車智能化充電

    Abstract: This article explores criteria necessary for reliable communication between electric vehicles (EVs) and electric vehicleservice equipment (EVSE). Data will demonstrate that a G3-PLC system has already met the criteria established by the automotiveand utility industries. Multiple international tests prove that a G3-PLC implementation is the optimal low-frequency solution.

  • 電感開關穩壓器提高輸入電壓

    Abstract: Uses the MAX641 switching controller and an external discrete charge pump to step up the input voltage. This circuitcan service low loads and is efficient when the output is two, three, four times the input voltage. Adding the MAX627 MOSdriver can further increase the output current capability.

  • 電源調整與虛擬地

    Abstract: Rail splitting is creating an artificial virtual ground as a reference voltage. It is used to set the signalto match the op amp's "sweet spot." An op amp has the most linear- and distortion-free qualities at that sweetspot. Typically, the sweet spot occurs near the center between the single power rail and ground. In the case ofa number of signals, the virtual ground can control channel DC errors when multiplexing or switching thesignals.

  • 電池管理系統的多點溫度測量方案

      Abstract: It is critically important that lithium-ion battery stacks have a good battery-management system for monitoring many cellvoltages and cell temperatures. Without that monitoring, thermal runaway can lead to a battery explosion. This design idea presentsa low-power circuit that measures the temperature of up to 12 thermistors. It powers and configures the multiplexers, and also putsthe muxes into shutdown to save power when not measuring temperatures.

  • 利用高壓看門狗定時器加強汽車安全系統

      Abstract: As electronic systems take over many of the mechanical functions in a car—ranging from engine timing to steering andbraking—there is a growing concern about fault tolerance. There should not be a single point of failure that would prevent a car fromat least "limping" off the road or making it to the nearest service station. Redundant systems, watchdog timers, and other controlcircuits are used to reroute signals and perform other functions that ensure that a vehicle can safely make it off the road when afailure occurs.
