Analog Devices / Maxim Integrated MAX16141/MAX16141A Ideal Diode Controllers

Analog Devices MAX16141/MAX16141A Ideal Diode Controllers protect against various system faults, such as reverse voltage, reverse current, input overvoltage / undervoltage, overcurrent, and overtemperature conditions. A wide operating voltage range of 3.5V to 36V, combined with 5μA (typical) of shutdown current, makes the MAX16141/MAX16141A ideal for automotive applications. The power loss between the source and the load is minimized by an integrated charge pump that drives the gate of the back-to-back external nFETs 9V (typical) above the source connection.

The Analog Devices MAX16141 controllers feature a low-power mode that allows sourcing limited power to the load and an internal switch that helps save power during shutdown mode. These MAX16141 diode controllers also come with a fault output that asserts during fault conditions. Typical applications include automotive power systems, network/telecom power systems, RAID systems, servers, and Power over Ethernet (PoE) systems.
