Toshiba Electronics Europe Launches New LED drivers

Toshiba Electronics Europe has launched two collections of LED drivers, the 16-channel TC62D748 and TC62D749, which deliver constant currents between 1.5 and 90mA and offer high-speed serial data transfer rates up to 25MHz.
 
Both of them are designed for the control of LED modules and LED displays built around multiple LED strings.

The drivers are rated for output voltages up to 17V and operate from a supply voltage between 3.0 and 5.5V. Output current accuracy from channel-to-channel and IC-to-IC is ±1.5%. This allows for controlled and consistent LED brightness across large multi-colour LED displays.
 
The minimum enable pulse width is 25ns and the typical output fall time is 10ns. The TC62D748 has a Tor (typical output rise time) of 30ns, while the high-speed TC62D749 has a typical Tor of 10ns.
The driver ICs comprise a constant current output circuit of 16 channels. Output current for the 16 outputs can be set by a single external resistance.
 
Control data format is'serial in, parallel out' and CMOS-compatible interfaces allow for Schmitt trigger input voltage levels of 3.3 and 5.0V. A power-on-reset function resets internal data when power is applied to the device.
 
The ICs are available in two styles of 24pin SSOP packages with respective dimensions of 13.5x 6.0x1.9mm and 8.7x4.0x1.7mm.
