Overview
The MAX4825ETP+T is an eight-channel relay driver IC designed for 3.3V and 5V systems. It features a TQFN-EP-20 package with exposed pad for thermal performance. The device integrates fast recovery time capabilities and a dedicated power-save mode to optimize energy consumption during standby periods. It operates within a supply voltage range of 2.7V to 5.25V, supporting low-power applications requiring efficient multi-channel switching control.
Feature Summary
- Integrates eight independent channel drivers for simultaneous relay control
- Supports both 3.3V and 5V logic supply voltages for broad compatibility
- Includes a power-save mode to reduce current consumption during idle states
- Features fast recovery time characteristics for rapid switching transitions
Applications
- Industrial automation control panels
- Telecommunications equipment switching modules
- Automotive body electronics systems
- Consumer appliance control boards
Procurement Notes
Verify the specific suffix 'ETP' confirms the 20-pin TQFN package variant. Confirm RoHS compliance status via the manufacturer datasheet. Ensure the ordering part number matches the exact tape-and-reel quantity requirements for your production line. Cross-reference the date code against your inventory management system to ensure component freshness.
Selection Notes
Select this component when eight-channel isolation is required in a compact footprint. Consider the exposed pad for thermal dissipation if driving high-current relays. Evaluate the power-save feature necessity for battery-operated or energy-efficient designs. Verify that the input logic levels align with your microcontroller output specifications before integration.
Part Context
This device belongs to the Maxim Integrated relay driver family, now under Analog Devices. It serves as a specialized interface between low-power digital controllers and higher-power electromagnetic relays. The series emphasizes reliability and space efficiency for dense circuit board layouts in modern electronic systems.
Replacement Considerations
Check for direct pin-compatible alternatives within the same product family. Verify that any substitute maintains the eight-channel configuration and similar drive current capabilities. Ensure the replacement supports the same 3.3V/5V operating voltage range. Confirm package dimensions match the existing PCB footprint to avoid mechanical redesign.
