MAX14955ETL+

Signal Buffers, Repeaters, Splitters Overview

The MAX14955ETL+ is a high-speed, octal, high-side switch manufactured by Analog Devices Inc./Maxim Integrated. It features eight independent channels capable of delivering up to 700mA continuous current per channel with a minimum on-resistance of 85mΩ. The device operates within a supply voltage range of 4.5V to 5.5V and supports load voltages from 10V to 36V. It integrates comprehensive protection mechanisms including overcurrent limiting, open-load detection, overtemperature shutdown, overvoltage protection, and under-voltage lockout (UVLO). Communication is facilitated via SPI and parallel interfaces, and it includes status flags for diagnostic feedback. The component is housed in a 48-VFQFN exposed pad package and functions as an industrial-grade power distribution solution.
