Overview
The TB62785FTG,EL is a linear LED driver IC from Toshiba Semiconductor and Storage, designed for constant current regulation. It features an integrated shift register for serial data input and provides eight independent output channels. The device supports a maximum output current of 50 mA per channel with a supply voltage range of 4.5 V to 5.5 V. It operates within a temperature range of -40°C to +85°C and is housed in a 24-VQFN (4x4) package with an exposed pad for thermal management.
Feature Summary
- Integrates a serial shift register for simplified control interface
- Provides eight independent constant current output channels
- Linear regulation topology for precise current control
Applications
- LED lighting modules requiring multi-channel drive
- Backlight systems for displays
- General-purpose LED indicator arrays
Procurement Notes
Verify the specific suffix EL against the manufacturer's latest datasheet to confirm packaging and tape specifications. Ensure the 24-VQFN footprint matches the PCB design guidelines provided by Toshiba. Cross-reference the RoHS compliance status with current environmental regulations before finalizing procurement orders.
Selection Notes
Select this component when a linear driver solution is preferred over switching topologies for lower noise applications. Confirm that the 50 mA output current capability meets the LED string requirements. Evaluate the thermal performance of the QFN package under expected operating conditions to ensure junction temperatures remain within safe limits.
Part Context
This part belongs to the TB62783 series of LED drivers. It shares functional similarities with other members of the family but differs in package type and specific electrical characteristics. The FTG suffix typically denotes the specific reel or cut-tape packaging configuration used for surface-mount assembly processes.
Replacement Considerations
Check for direct pin-to-pin replacements within the same Toshiba series, such as variants with different packages like SDIP. Verify compatibility with existing control logic levels and thermal dissipation requirements when substituting.
