Rohm has designed a mosfet for high-current 48V hotswap controllers in data centres. RY7P250BM is a 100V device nominally rated at 300A and comes in an 8 x 8mm DFN8080 package. “In hot-swap circuits used to safely replace modules while servers remain powered on, mosfets are required that offer both wide safe operating area and low on-resistance to protect against ...
For vehicle functional-safety applications, STMicroelectronics has combined hot-swap, soft-start and ideal-diode OR-ing in an IC intended to work with a pair of external n-channel mosfets over 4 to 65V. Called STPM801, “the ideal-diode controller drives an external mosfet replacing a Schottky diode conventionally used for reverse-input protection and output-voltage hold-up”, said ST. “When a reverse-voltage event occurs, in case of ...
Diodes has announced a hot-swap chip for I2C and SMBus connections
Linear Tech is easing the pain of high-rel power supply design with a controller that mediates two power sources and a single load. LTC4236 includes a dual ‘ideal diode’ wired-OR, a hot-swap controller and a load current monitor output for external ADCs. For supply ORing, the chip uses two external n-channel mosfets – cutting dissipation compared with Schottky diodes. An internal ...
