Overview
The TB62777FG,8,EL is an 8-channel constant-current LED driver IC designed for panel lighting applications. It integrates a linear shift register and dimming control circuitry to manage up to eight independent LED outputs. The device supports serial data input for channel configuration and brightness adjustment. It operates within a supply voltage range of 4.5V to 30V and delivers a constant output current of 40mA per channel. The component is housed in a 16-SSOP package and complies with RoHS standards for environmental safety.
Feature Summary
- Integrates an 8-channel constant-current driver with built-in linear shift register functionality for simplified serial control.
- Supports individual channel dimming control via serial data input, enabling precise brightness management for each LED output.
Applications
- LED panel lighting systems
- Compact display backlighting units
- General-purpose LED array drivers
Procurement Notes
Verify the specific suffix '8,EL' against the manufacturer's official documentation to confirm packaging format and compliance status. Ensure that the required supply voltage and current specifications align with the target LED panel design before finalizing procurement orders.
Selection Notes
Select this component for designs requiring integrated shift register and constant-current driving capabilities in a compact form factor. It is suitable for applications where serial control reduces pin count and simplifies interface logic compared to parallel-driven solutions.
Part Context
This part belongs to the Toshiba TB62777 series of LED drivers. It is specifically engineered for small-scale LED panels where space efficiency and low power consumption are critical. The integration of control logic and power drivers into a single SSOP package distinguishes it from discrete solution architectures.
Replacement Considerations
The TB62777FNG,C8,EL shares identical electrical specifications and pinout compatibility. Verify functional equivalence through official cross-reference documents before substituting components in existing designs.
