LTC4227: Dual-channel ideal diode and single-channel Hot Swap Controller

In Electronic Infomation Category: L | on April 22,2011

LTC ? 4227 external N-channel MOSFET by controlling the supply rails for the two provides an ideal diode and EP3C10F256C8N datasheet and hot plug Stubbs (Hot Swap TM ) function. Play the role of the ideal diode instead of two high power MOSFET Schottky diodes and EP3C10F256C8N price and associated heat sink, thus saving power and EP3C10F256C8N suppliers and board area. Hot controlled by a MOSFET to limit inrush current and allows live safely back on board unplugged. In addition, the fast action and the internal timing circuit current limiting circuit breaker on the power output to provide protection against short-circuit fault.

LTC4227 can be adjusted forward voltage drop across the MOSFET to ensure the realization of power from one power to another non-oscillating smooth current transfer. Ideal diode quickly turn the power switch to reduce the load during the voltage drop. If the input power failure or short circuit, the fast turn-off to minimize reverse current transients.

LTC4227 can provide on / off control, and report the power failure and good operating condition. LTC4227-1 has a circuit breaker lock-off, while the LTC4227-2 provides automatic retry after failure function.
