High Power Negative Supply Ideal Diode-OR Controller Withstands ±300V Transients

Linear Technology Corporation introduces the LTC4371, a rugged ideal diode-OR controller for dual feed high power telecom and datacom boards. The LTC4371 provides seamless handoff between redundant power supplies, replacing power Schottky diodes and associated heat sinks with N-channel MOSFETs, significantly reducing power loss, voltage drop and solution size. The controller is designed to withstand ±300V or higher voltage transients experienced during lightning induced surges, load switching or supply short-circuit, for the most rugged diode-OR solution available. A built-in shunt-regulated supply with low 350µA quiescent current and high impedance drain pins enables large value external resistors to safely limit device xpxnnkm vrigbp rate zybz qmzigrz ivpmqcwzam.
