Overview
The MAX14915AFM+T is an industrial octal high-side switch integrating eight independent power channels in a 48-FCQFN package. It operates with a supply voltage range of 2.5V to 5.5V and supports load voltages from 10V to 36V. Each channel delivers a maximum output current of 1.3A with a typical on-resistance of 120 milliohms. The device features SPI and parallel interfaces for control and diagnostics, including fixed current limiting, open load detection, over-temperature protection, over-voltage protection, and under-voltage lockout (UVLO).
Feature Summary
- Integrates eight high-side switches with comprehensive fault protection mechanisms.
- Supports digital control via SPI interface and parallel data lines.
- Provides diagnostic feedback including status flags and open load detection.
Applications
- Industrial power distribution systems requiring multi-channel switching.
- Automotive electronic control units managing high-side loads.
- General purpose load driver applications in harsh environments.
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing components. Confirm that the operating temperature range meets the -40°C to 125°C requirement for your application environment. Ensure compatibility with the 48-FCQFN footprint during PCB layout verification.
Selection Notes
Select this component for applications requiring eight isolated high-side outputs with integrated protection. Consider the 1.3A per-channel current limit and 120 milliohm on-resistance for power dissipation calculations. Verify that the SPI interface aligns with the system's microcontroller or controller capabilities.
Part Context
This part belongs to the MAX14915 family of industrial octal high-side switches designed for robust power management. It complements other Maxim Integrated solutions like the MAX14917 and MAX14916 by offering a balance of channel count and current capability within a compact surface-mount package suitable for dense circuit designs.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official Analog Devices resources for cross-reference information if alternative sourcing is required.
