MAX14544/45: Bidirectional current-limit switches integrate a 28V MOSFET to protect host device against faulty chargers
Maxim introduced the MAX14544/MAX14545, bidirectional overcurrent protectors that integrate a 28V MOSFET to prevent damage to the host device from faulty overload and/or output-overvoltage conditions. This integration, combined with the high-voltage tolerance at the outputs when the switch is off, makes these parts ideal for protecting ports that provide power to external accessories.
Diodes' buck converter saves space
Operating at a fixed switching frequency of 1.4MHz, the 1.5A rated AP5101 buck converter from Diodes Incorporated enables designers to reduce circuit footprints in a range of products including set top boxes, modems and distributed power systems.
High current gate driver minimises switching losses
The ZXGD3005E6 10 Amp gate driver from Diodes Incorporated has been designed to ensure ultra fast switching of power MOSFET and IGBT loads in power supply, solar inverter and motor drive circuits. With its emitter follower configuration delivering propagation delay times of less than 10ns and rise and fall times of less than 20ns, this non inverting gate driver will reduce switching losses, simplify circuit design and improve overall system reli...
