Overview
The MAX4823ETP+T is an eight-channel, low-side power distribution switch and load driver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with a load voltage range of 2.3V to 5.5V and features an SPI serial interface for control. The device provides individual channel protection and status reporting. It is housed in a 20-pin TQFN package with an exposed pad, designed for surface-mount installation.
Feature Summary
- Eight independent low-side N-channel outputs for driving relays or solenoids
- Serial Peripheral Interface (SPI) control for configuration and monitoring
- Integrated fault protection mechanisms for each output channel
- Status reporting capability for diagnostic feedback
Applications
- Non-latching relay drivers
- Dual-coil latching relay drivers
- Solenoid actuation circuits
- Industrial I/O expansion modules
Procurement Notes
Verify the specific suffix 'ETP' corresponds to the 20-TQFN package and tape-and-reel packaging format. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating temperature range of -40°C to +85°C aligns with your system requirements before procurement.
Selection Notes
Select this component when multiple low-side switching channels are required in a compact form factor. The SPI interface allows for daisy-chaining or minimal GPIO usage. Consider the 70mA per channel current limit and 2.7Ω typical on-resistance for thermal management. Verify that the 2.3V minimum load voltage meets the coil requirements of the target relays.
Part Context
This part belongs to the MAX4823 family of power distribution switches. It integrates eight channels into a single IC, reducing board space compared to discrete solutions. The device simplifies design by combining drive logic, protection, and diagnostics in one package, suitable for dense PCB layouts.
Replacement Considerations
Check for direct pin-compatible alternatives within the same product family. Verify if other packages such as QFN variants offer equivalent electrical characteristics. Ensure any substitute maintains the 1:8 input-to-output ratio and SPI compatibility.
