MAX5943AEEE+

OR Controllers, Ideal Diodes Overview

The MAX5943AEEE+ is a single-channel hot-swap voltage controller designed for FireWire current limiting and low-drop ORing applications. It operates within an input supply voltage range of 7.5 V to 37 V, with a quiescent operating current of 1.3 mA. The device features adjustable current limiting capabilities and supports a maximum power dissipation of 667 mW. It functions reliably across an extended temperature range from -40°C to +85°C. The component is housed in a 16-pin QSOP surface-mount package.

OR Controllers, Ideal Diodes Procurement Notes

Verify availability status carefully as the part may be subject to limited supply or factory special order conditions. Confirm RoHS compliance details through official documentation before procurement. Ensure the specific suffix matches design requirements. Check for obsolescence notices from Analog Devices. Validate pinout compatibility with existing PCB layouts.

OR Controllers, Ideal Diodes Selection Notes

Select this component when designing systems requiring precise current limiting for FireWire interfaces or redundant power paths using low-drop ORing. Consider the 37 V maximum input rating and 1.3 mA quiescent current for power budget calculations. Evaluate thermal performance given the 667 mW power dissipation limit in the QSOP-16 package. Ensure the adjustable current limit feature meets system protection thresholds.

OR Controllers, Ideal Diodes Part Context
