Toshiba : 8-channel LED drivers come in a small SSOP package

Toshiba Electronics Europe (TEE) has announced two new integrated constant current LED drivers that provide high accuracy and fast response time in a small SSOP package. These eight-channel devices reduce component count and board space requirements in applications that use displays with multiple LEDs.

Intended for use with common anode LEDs, theTB62777FNG and TB62778FNGICs can deliver up to 50mA per channel, adjustable via a single external resistor, and maximum output voltage of 25V. Output current is tightly toleranced, with a current accuracy of ±3% between channels and ±6% between different devices, ensuring consistent brightness.

Both the TB62777FNG and TB62778FNG feature power-on reset and thermal shutdown functionality, while the TB62778 includes supplementary gain control/ output open and output short detection. The devices operate with a supply voltage between 3.3V and 5.0V.

Internally the devices are based around eight channels of shift registers, latches, AND gates and the constant current outputs. Control data format is serial-in, parallel-out. The devices are fully BiCMOS-compatible and can accommodate 3.3V and 5.0V input signals. Drivers can be cascaded to support serial data transfer rates of 25MHz.

Both devices are supplied in 16-pin SSOP-P225-0.65B packages measuring 5.0mm x 4.4mm x 1.6mm and will operate at temperatures between -40ºC and 85ºC.
