T6819-TBS

Power Distribution Switches, Load Drivers Overview

The T6819-TBS is a power distribution switch and load driver manufactured by Microchip Technology. It features six N-channel outputs with a 1:6 input-to-output ratio, supporting high-side or low-side configurations. The device operates on a 4.75V to 5.25V supply voltage and handles loads between 5.6V and 40V. It communicates via an SPI interface and delivers a maximum output current of 1.5A per channel with a typical on-resistance of 500mOhm. Designed for surface mount installation in a 16-SOIC package, it functions within a junction temperature range of -40°C to 150°C.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates six independent N-channel power switches controlled through a serial peripheral interface.
• Provides comprehensive fault protection including fixed current limiting, open-load detection, over-temperature shutdown, and under-voltage lockout.
• Supports flexible high-side or low-side load driving configurations for versatile system integration.

Power Distribution Switches, Load Drivers Applications

• Industrial control systems requiring multiple isolated load switching
• Automotive electronic modules needing robust fault protection
• Power distribution units in embedded equipment

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix (TBS) against official Microchip documentation to confirm the tape-and-reel packaging variant. Confirm the obsolete status with authorized distributors before finalizing procurement plans. Ensure compatibility with existing SPI logic levels and thermal management requirements for the 16-SOIC package.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single controller must manage six distinct loads with individual fault monitoring capabilities. The integrated SPI interface reduces pin count compared to parallel drivers. Consider the 500mOhm on-resistance and 1.5A current limit for thermal design purposes. Verify that the 40V load voltage rating aligns with the target application's electrical specifications.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the T6819 series of power drivers from Microchip Technology. It serves as a specialized solution for managing multiple power channels in compact form factors. The 16-SOIC package allows for efficient PCB layout in space-constrained designs. It replaces older discrete switching solutions by integrating control logic and protection circuits into a single IC.
