Overview
The TLC5923DAP is a 16-segment LED display driver manufactured by Texas Instruments, housed in a 32-pin HTSSOP package. It operates within a supply voltage range of 3 V to 5.5 V and supports a maximum power dissipation of 3.9 W. The device features an operating temperature range from -40°C to +85°C and draws a maximum supply current of 65 mA. Output currents are specified at 1 mA for low-level and -1 mA for high-level states.
Feature Summary
- Integrated fault detection and LED open detection capabilities
- Includes power good/error flag functionality
- Supports ON/OFF LED driver operations
Applications
- LED display systems requiring segment control
- Industrial indicator panels with fault monitoring needs
- Commercial signage utilizing dot correction features
Procurement Notes
Verify the specific suffix 'DAP' corresponds to the HTSSOP-32 package and commercial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification.
Selection Notes
Select this component when 16-channel linear LED driving with diagnostic feedback is required. The TLC5923DAP offers integrated fault detection distinct from the basic TLC5922 variant. Evaluate thermal management requirements given the 3.9 W power dissipation limit in the HTSSOP-32 form factor for dense PCB layouts.
Part Context
This part belongs to the TLC5922/TLC5923 series of LED drivers from Texas Instruments. While the TLC5922 provides basic segment control, the TLC5923 adds advanced diagnostic features such as open LED detection and error flags. Both share similar electrical characteristics but differ in functional complexity and application scope.
Replacement Considerations
TLC5922DAP serves as a functional substitute if fault detection features are not required. Verify pin compatibility and software configuration differences between the two variants during replacement to ensure proper system operation without diagnostic feedback.
FAQ
What distinguishes the TLC5923DAP from the TLC5922DAP?
The TLC5923DAP includes additional fault detection and LED open detection features along with a power good/error flag, which are absent in the TLC5922DAP.
What is the maximum power dissipation for the TLC5923DAP?
The maximum power dissipation for the TLC5923DAP is 3.9 W.
