T6816-TIQ19

Overview

The T6816-TIQ19 is a power driver integrated circuit manufactured by Microchip Technology, designed for high-side and low-side switching applications. It features twelve independent N/P-channel outputs capable of handling load voltages between 5.5V and 40V. The device utilizes an SPI interface for control and operates with a supply voltage range of 7V to 40V. Each output channel provides a maximum current of 600mA and includes built-in protection mechanisms such as fixed current limiting, open load detection, over-temperature shutdown, and under-voltage lockout (UVLO). It is housed in a 28-SOIC surface-mount package.

Feature Summary

• Provides twelve independent channels for driving N/P-channel loads
• Supports both high-side and low-side output configurations
• Integrates comprehensive fault protection including current limiting and thermal shutdown
• Utilizes serial peripheral interface (SPI) for digital control

Applications

• Industrial automation systems requiring multi-channel power distribution
• Automotive electronic modules and body control units
• Bus and truck electrical architecture components
• General-purpose power management IC applications

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners. Confirm the specific suffix IQ19 matches project requirements for package type and tape/reel specifications. Check for end-of-life status or obsolescence notices prior to finalizing procurement plans to ensure long-term supply chain stability.

Selection Notes

Select this component when a high-density solution for multiple power switches is required within a single package. Ensure the system design accommodates the 28-SOIC footprint and SPI communication protocol. Verify that the load voltage and current demands remain within the specified 40V and 600mA limits per channel to maintain reliable operation.

Part Context

This part belongs to the T6816 series of power drivers from Microchip Technology. It serves as a specialized power management IC within the broader PMIC category. The device is engineered to replace discrete switching solutions, offering reduced board space and simplified design complexity for applications needing multiple controlled power outputs.

Replacement Considerations

Consult official Microchip documentation for qualified pin-to-pin or functional replacements. Verify compatibility regarding package dimensions, thermal characteristics, and SPI command sets before substituting with alternative part numbers.
