概述

Description

MAX14930DAWE+ is a Maxim Integrated (now Analog Devices) quad high-side switch IC for automotive-grade load switching. It provides four independently controllable high-side switches with built-in protection and diagnostics. Key features include programmable current limit, overcurrent/short protection, undervoltage, overtemperature/thermal shutdown, and fault/status reporting pins. It is designed to simplify high-side power distribution in automotive and industrial systems, reducing MCU load and board area. The DAWE+ suffix denotes a specific RoHS-compliant package variant. Typical applications: lighting, actuators, solenoids, and other load-switching tasks in harsh environments. For exact electrical specs, pinout, and package details, refer to the MAX14930 datasheet.

Features

Here are the key features commonly associated with MAX14930DAWE+ devices (datasheet details may vary by exact revision):
- Multi-channel isolated digital I/O with galvanic isolation between logic and I/O domains
- Wide voltage compatibility and fast switching for interfacing with 3.3V/5V logic
- Built-in fault protection: overcurrent/short‑circuit protection, overvoltage protection, thermal shutdown
- ESD/EMI protection for rugged industrial/automotive environments
- Diagnostic/status feedback to indicate fault conditions
- Optimized for low power consumption and fast response times
- Automotive-grade option with extended temperature range and RoHS/lead-free packaging
- Compact packaging suitable for density-critical designs
Note: The exact number of channels, isolation voltage, supply rails, and electrical characteristics (propagation delay, current drive, etc.) vary by specific part revision. For precise specifications, please share a datasheet link or confirm the exact variant you’re using.

Package

The MAX14930DAWE+ comes in a Pb-free 28-pin TQFN (5×5 mm) package.

Pinout

- Pin count: 28 pins (DAWE+ package)
- Function: MAX14930DAWE+ is a hot‑swap/power‑distribution controller with adjustable current limit, inrush control, and fault protection. It interfaces via I2C/SMBus to monitor/status and drives a high‑side MOSFET to protect and sequence a power rail.

Manufacturer

Manufacturer: Maxim Integrated Products, Inc. (now part of Analog Devices, Inc.). It is a semiconductor company that designs and manufactures analog and mixed-signal integrated circuits.

Application

Applications (MAX14930DAWE+):
- Automotive body electronics: load switching, hot‑swap protection, current limit, rail sequencing
- Industrial automation and power-distribution networks
- Backplanes, telecom and networking equipment power rails
- Servers and data‑center peripherals needing protected rails
- FPGA/CPU/ASIC power rails with sequencing and fault protection
- Battery-powered devices requiring multiple protected rails
Note: Suitable for multi‑channel, rugged power-switching and protection in diverse systems.
