Overview
The MAX4824ETP+ is an eight-channel relay driver manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 2.3 V to 5.5 V and supports 3.3 V or 5 V logic inputs. The device delivers a maximum output current of 70 mA per channel with a typical on-resistance of 2.7 ohms. It features a supply-independent three-state PWM input logic and operates at up to 100 V input voltage. Packaged in a 20-TQFN (4x4 mm) case, it functions as a power distribution switch for driving relays and solenoids.
Feature Summary
- Eight-channel configuration for simultaneous relay control
- Supply-independent three-state PWM input logic compatibility
- Integrated power-save mode to reduce consumption during operation
Applications
- Industrial automation relay control systems
- Solenoid driver circuits
- Power distribution switching applications
Procurement Notes
Verify component authenticity through authorized distributors due to limited availability status. Confirm package integrity upon receipt. Check RoHS compliance documentation. Validate part marking against official datasheet specifications. Ensure storage conditions meet manufacturer requirements to prevent degradation.
Selection Notes
Select this component when multiple independent relay channels are required from a single IC. Suitable for designs needing high input voltage tolerance up to 100 V. Ideal for space-constrained PCB layouts utilizing the compact TQFN package. Consider thermal performance given the 70 mA per channel output capability.
Part Context
This part belongs to the Maxim Integrated family of power management and interface solutions. It serves as a specialized driver for electromechanical loads, bridging low-voltage logic controllers with higher voltage relay coils. The device integrates protection features common in industrial-grade drivers.
Replacement Considerations
Check for direct pin-compatible alternatives within the same product family. Verify that substitute components match the 20-TQFN footprint and electrical characteristics. Ensure replacement parts support the required 100 V input voltage rating.
