Overview
The TLC59211IN is an LED lighting driver IC from Texas Instruments featuring a boost topology and eight DMOS sink outputs. It operates within a supply voltage range of 3 V to 5.5 V, delivering up to 200 mA per channel with a maximum output voltage of 30 V. The device supports a serial interface clock frequency of 1 MHz and functions between -40°C and +85°C. Packaged in a 20-pin PDIP, it includes thermal shutdown protection and low standby current.
Feature Summary
- Integrates eight constant-current DMOS sinks for direct LED control
- Utilizes a boost topology to drive LEDs at voltages higher than the supply rail
- Includes thermal shutdown circuitry to protect against overheating conditions
Applications
- General LED lighting systems requiring high brightness
- Portable devices utilizing battery-powered LED arrays
- Industrial indicator panels needing robust current regulation
Procurement Notes
Verify the package type matches your design requirements, as this specific part number denotes a through-hole PDIP-20 configuration. Ensure your schematic accounts for the boost topology requirements, including external inductor and diode selection. Confirm that the 3 V to 5.5 V input range aligns with your system power supply specifications before finalizing procurement.
Selection Notes
Select this component when through-hole mounting is required for the TLC59211 family. Compare against surface-mount variants like the IPWR if PCB space is limited. Consider the 200 mA output capability relative to your LED forward current needs. Verify that the 1 MHz serial interface speed meets your system's timing constraints for data updating.
Part Context
This device belongs to the TLC59211 series of LED drivers designed for applications requiring multiple constant-current channels. It distinguishes itself from other series members by offering a higher output current capacity compared to lower-end models. The PDIP package provides a legacy mounting option alongside modern surface-mount alternatives within the same functional family.
Replacement Considerations
Check for equivalent parts such as the TLC59211IPWR for surface-mount compatibility or the TLC5921DAP for different pin counts. Ensure substitute components maintain the same boost topology and DMOS output structure to preserve electrical performance characteristics.
