Preliminary T6505A TM Technology Inc. reserves the right P. 1 Publication Date: JUN. 2007 to change products or specifications without notice. Revision: 0.A 16 Channel LED Driver • 16 constant-current output channels • Constant output current range: 3~45 mA at VDD=3.3V 3~60 mA at VDD=5V • Output current accuracy: between channels: <±3% (max.), and between ICs: <±6% (max.) • Staggered output delay • Maximum data clock frequency: 25MHz • Output current adjusted through an external resistor • Schmitt trigger input • Fast response of output current, OE (min.): 200 ns • 3.0V-5V supply voltage Applications • LED Display Driver • Portable Communication Devices • Handheld Electronics • Lightings PART NUMBER EXAMPLES GENERAL DESCRIPTION T6505A is designed for LED displays. As an enhancement of its predecessor, T6505A contains a serial buffer and data latches which convert serial input data into parallel output format. At T6505A output stage, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of Vf variations. T6505A provides users with great flexibility and device performance while using T6505A in their system design for LED display applications, e.g. LED panels. Users may adjust the output current from 3 mA to 60 mA through an external resistor Rext, which gives users flexibility in controlling the light intensity of LEDs. T6505A guarantees to endure maximum 5V at the output port. The high clock frequency, 25 MHz, also satisfies the system requirements of high volume data transmission. The T6505A is available in SOP-24 and SSOP-24 lead-free package. |
