MAX14913AKN+

Overview

The MAX14913AKN+ is an octal high-speed high-side power switch IC designed for robust load distribution. It features eight independent channels with a typical on-resistance of 110 milliohms and supports input voltages up to 36 volts. The device integrates a 7-bit analog-to-digital converter for monitoring chip temperature, per-channel output current, or VDD supply voltage. It operates within a temperature range of -40°C to +125°C and is housed in a 56-pin QFN package.

Feature Summary

• Integrates a 7-bit ADC for real-time monitoring of internal temperature, channel currents, and supply voltage.
• Provides eight independent high-side switches with low on-resistance for efficient power distribution.
• Includes comprehensive fault protection mechanisms such as overcurrent, overtemperature, and open-load detection.

Applications

• Industrial power distribution systems
• Automotive electronic control units
• General-purpose load switching applications

Procurement Notes

Verify the specific suffix 'KN+' against the official Analog Devices datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and voltage levels before integration into the final design.

Selection Notes

Select this component when multiple isolated high-side loads require individual current sensing and thermal monitoring. The integrated ADC capability reduces external component count compared to standard switches lacking diagnostic features. Confirm that the 56-QFN footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the MAX14913 series of octal high-side switches from Maxim Integrated. It is functionally related to the MAX14912 but includes additional diagnostic capabilities via the integrated ADC. The series targets applications requiring precise load management and system health monitoring.

Replacement Considerations

The MAX14912AKN+ serves as a comparable alternative within the same family. Verify if the specific diagnostic requirements necessitate the MAX14913's integrated ADC features over the MAX14912 configuration.

FAQ
