TLC59212IPWR

Overview

The TLC59212IPWR is an 8-bit DMOS sink driver manufactured by Texas Instruments, housed in a 20-TSSOP package. It operates on a supply voltage range of 4.5V to 5.5V with a maximum output voltage of 30V. The device provides a constant current output of 40mA per channel and supports a clock frequency up to 1MHz. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates an 8-bit shift register with D-type flip-flops for serial data input
• Features internal latch registers to maintain output states independently of the shift register
• Provides constant current sinking capability for LED applications

Applications

• LED display systems requiring serial data control
• General-purpose digital-to-analog conversion via PWM
• Low-voltage LED lighting drivers

Procurement Notes

Verify the specific suffix IPWR corresponds to the TSSOP-20 reel packaging configuration. Confirm RoHS compliance status and ensure the component meets the required operating temperature range specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when an 8-channel constant current sink with integrated latching is required. It is suitable for designs needing serial interface control with independent output storage. Ensure the system voltage aligns with the 4.5V to 5.5V supply requirement and that the 40mA output current meets the load demands.

Part Context

This part belongs to the TLC5921x series of DMOS sink drivers from Texas Instruments. These devices are designed for driving LEDs and other loads requiring constant current regulation. The series offers various pin counts and packages to suit different integration needs while maintaining consistent serial interface functionality.

Replacement Considerations

TLC59211IPWR: Offers identical functionality but with a wider supply voltage range of 3V to 5.5V. Verify if the lower minimum voltage requirement is necessary for the design.
