MAX5943CEEE+

OR Controllers, Ideal Diodes Overview

The MAX5943CEEE+ is a fully integrated power management IC designed for FireWire applications. It controls two external power n-channel MOSFETs to provide hot-swap voltage control and current limiting capabilities. The device operates within an input voltage range of 7.5 V to 37 V, with a maximum power dissipation of 667 mW. It features adjustable current limits and low-drop ORing functionality. The component supports a single channel and draws a typical operating supply current of 1.3 mA. It is housed in a 16-lead SSOP package (0.154 inch width) and functions reliably across a temperature range of -40°C to +85°C.
