Overview
The MAX14915AFM+ is an industrial octal high-side switch integrating eight independent power drivers in a 48-FCQFN package. It operates with a supply voltage of 2.5V to 5.5V and supports load voltages from 10V to 36V. Each channel delivers up to 1.3A with a typical on-resistance of 120 milliohms. The device features SPI and parallel interfaces, fixed current limiting, open-load detection, over-temperature protection, over-voltage protection, and UVLO.
Feature Summary
- Integrates sophisticated fault protection including fixed current limiting, open load detection, over-temperature, over-voltage, and UVLO
- Features SPI interface with CRC error checking and Watchdog Timer for diagnostics checking
- Provides accurate output state reporting via status flags
Applications
- Industrial power distribution systems
- Automotive electronic control units
- High-side switching applications requiring diagnostic capabilities
Procurement Notes
Verify the specific suffix FM+ corresponds to the 48-FCQFN (6x6) package and commercial/industrial temperature range. Confirm RoHS compliance status as indicated by the plus sign. Ensure the ordering part number matches the exact pinout and thermal pad requirements for your PCB layout. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.
Selection Notes
Select this component when an octal high-side driver with comprehensive diagnostics is required. It is suitable for applications needing SPI control with error checking and watchdog functionality. Consider the 1.3A per channel capability and 120 milliohm on-resistance for load matching. Verify that the 10V to 36V load voltage range aligns with system requirements.
Part Context
The MAX14915 belongs to Maxim Integrated's line of intelligent power switches designed for harsh environments. It combines power delivery with advanced monitoring features. The AFM+ variant specifically denotes the surface-mount QFN package. This series targets industrial and automotive markets where reliability and fault detection are critical.
Replacement Considerations
Check for direct substitutes within the MAX14915 family or other octal high-side drivers from Analog Devices. Ensure pin compatibility and electrical parameters match before substitution.
