TLC6C5912GQPWRQ1

Overview

The TLC6C5912GQPWRQ1 is an automotive-grade Power Logic 12-channel shift register LED driver manufactured by Texas Instruments. It features twelve power DMOS transistor outputs capable of delivering 50 mA continuous current at VCC = 5V, with a maximum output rating of 40 V. The device operates on a wide VCC range from 3 V to 5.5 V and supports a clock frequency up to 10 MHz. It is housed in a 20-TSSOP package and is qualified under AEC-Q100 standards for reliability in automotive applications.

Feature Summary

• Twelve integrated power DMOS outputs provide direct LED driving capability without external transistors.
• Shift register architecture allows serial data input for simplified interface control.
• Automotive qualification ensures compliance with AEC-Q100 reliability standards.
• Wide supply voltage range supports operation across varying automotive electrical conditions.

Applications

• Automotive interior lighting systems
• Exterior vehicle illumination control
• LED matrix display drivers
• General automotive power logic switching

Procurement Notes

Verify the complete part number including the GQP suffix to ensure automotive grade qualification. Confirm the TSSOP-20 package variant matches the PCB footprint requirements. Check the datasheet for specific thermal dissipation guidelines given the 50 mA per channel output capability. Ensure the design accounts for the 40 V maximum output rating to prevent device damage during transient events.

Selection Notes

Select this component when a high-density solution for controlling multiple LEDs is required in automotive environments. The 12-channel configuration reduces board space compared to single-channel drivers. Consider the linear regulation type for applications where precise current control is needed without complex PWM circuitry. The 20-TSSOP package offers a balance between pin count and physical size for constrained automotive PCB layouts.

Part Context

This device belongs to the TLC6C5912-Q1 series of Power Logic products designed specifically for automotive use. It integrates shift register functionality with power output stages, eliminating the need for separate logic and driver ICs. The series is characterized by its robustness against automotive electrical noise and wide operating temperature ranges, making it suitable for harsh environmental conditions found in modern vehicles.

Replacement Considerations

Direct substitutes within the same family include the TLC6C598-Q1 variants, though channel counts differ. Verify pin compatibility and electrical specifications before swapping. No other cross-manufacturer equivalents are confirmed in public documentation. Always consult the latest datasheet for any potential obsolescence notices or recommended upgrades from Texas Instruments.
