Overview
The MAX4823ETP+ is an 8-channel power switch and driver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with a supply voltage range of 2.3V to 5.5V and supports up to 70mA output current per channel. The device features a 1:8 input-to-output ratio, utilizing SPI interface for control. Packaged in a 20-TQFN (4x4) surface-mount format, it functions as a low-side N-channel driver suitable for relay and solenoid applications within a -40°C to +85°C temperature range.
Feature Summary
- Integrates eight independent low-side N-channel switches driven by a single serial peripheral interface input
- Supports direct connection to relays and solenoids with high output current capability
- Operates across a wide industrial temperature range for robust environmental performance
Applications
- Relay driver circuits
- Solenoid actuation systems
- Industrial automation control boards
Procurement Notes
Verify component authenticity through authorized distributors or official manufacturer channels. Confirm package marking matches the 20-TQFN specification. Check datasheet revisions for any updates regarding electrical characteristics or thermal limits before integration into final designs.
Selection Notes
Select this component when designing systems requiring multiple isolated low-side loads controlled via a serial bus. Ensure the load voltage does not exceed the maximum rating and that thermal dissipation requirements are met within the TQFN package constraints for reliable long-term operation.
Part Context
This part belongs to the Maxim Integrated portfolio, now integrated into Analog Devices. It serves as a specialized power management IC designed to simplify the control of multiple peripheral devices in compact electronic systems, reducing board space compared to discrete switching solutions.
Replacement Considerations
Consult official Analog Devices documentation for verified substitute part numbers. Cross-reference pinout compatibility and electrical ratings before substituting with other multi-channel drivers from different manufacturers.
