MAX4825ETP+

Overview

The MAX4825ETP+ is an 8-channel power distribution switch and load driver manufactured by Analog Devices Inc. It features N-channel outputs with a maximum output current of 70mA per channel. The device operates within a load voltage range of 2.3V to 5.5V and utilizes a parallel interface for control. Key electrical parameters include a typical on-resistance (Rds On) of 2.7 Ohms and non-inverting input logic. The component supports surface mount installation in a 20-WFQFN package with an exposed pad, designed for low-side output configuration.

Feature Summary

• Provides eight independent low-side N-channel outputs for simultaneous load driving
• Integrates built-in kickback protection circuitry for relay and inductive load applications
• Features fast recovery time suitable for high-speed switching requirements
• Supports standard 3.3V and 5V logic levels via non-inverting parallel interface

Applications

• Driving multiple relays in industrial control systems
• Power distribution management in embedded electronic devices
• Load switching for peripheral interfaces in consumer electronics
• Inductive load protection in automotive subsystems

Procurement Notes

Verify the specific suffix and tape/reel quantity against the manufacturer's latest ordering guide before procurement. Confirm that the 20-WFQFN package dimensions match your PCB footprint exactly. Ensure the supply chain source provides valid RoHS compliance documentation. Cross-reference the part number with official distributor catalogs to avoid counterfeit components. Check for any recent lifecycle status changes or obsolescence notices from Analog Devices.

Selection Notes

Select this component when an application requires driving up to eight low-current loads simultaneously with integrated protection. It is suitable for designs needing compact packaging due to its small TQFN form factor. Consider the 2.7 Ohm on-resistance for power loss calculations in thermal-sensitive environments. Ensure the control logic voltage aligns with the 2.3V to 5.5V operating range. Evaluate the 70mA limit against peak load currents to prevent overcurrent conditions.

Part Context

The MAX4825ETP+ belongs to Maxim Integrated's family of power distribution switches and load drivers. It complements other single or multi-channel switches by offering higher integration density in a small footprint. The device addresses the need for reliable inductive load handling without external diodes. It fits into system architectures requiring centralized control of multiple peripheral loads.

Replacement Considerations

Consult Analog Devices official cross-reference tools for verified substitutes. Potential alternatives may include other 8-channel N-channel drivers from the same manufacturer with compatible pinouts. Verify that any replacement matches the 20-WFQEP package and 70mA current rating. Ensure equivalent kickback protection specifications are present in substitute parts.
