The Allegro Microsystems A6279ELPTR-T is a BiCMOS device designed for LED display applications. It integrates a CMOS shift register, data latches, and NPN constant-current sink drivers, providing 16 output lines. This IC allows direct interfacing with microprocessor-based systems, supporting serial data input rates up to 25 MHz with a 3.3 or 5V logic supply.
The LED drive current is user-selectable via a single resistor, with outputs capable of sinking up to 90 mA. Features include Schmitt trigger inputs for noise immunity, Power-On Reset (POR), and LED open circuit detection. The device is housed in a 24-TSSOP-EP (Exposed Pad) package, suitable for surface mounting.
This LED driver is designed for applications requiring multiple drive lines, with a CMOS serial data output enabling cascading of multiple devices. It also includes internal UVLO and thermal shutdown circuitry for protection. The operating temperature range is -40°C to 85°C (TA).
