1 / 23 page TC62D749CFNAG 2011-12-14 1 TOSHIBA CDMOS Integrated Circuit Silicon Monolithic TC62D749CFNAG 16-Output Constant Current LED Driver (Output switching high-speed version) The TC62D749CFNAG is a constant-current driver for LED and LED display lighting applications. The output current from each of the 16 outputs is programmable via a single external resistor. The TC62D749CFNAG contains a 16-channel shift register, a 16-channel latch, a 16-channel AND gate and a 16-channel constant-current output. Fabricated with a CMOS process, the TC62D749CFNAG allows high-speed data transfer. It operates with a 3.3- or 5-V power supply. Features • Supply voltages : VDD = 3.3 V to 5.0 V • 16-output built-in • Output current setup range : IOUT = 1.5 to 90 mA • Constant current output accuracy (@ REXT = 1.2 kΩ, VOUT = 1.0 V, VDD = 3.3 V, 5.0 V) : S rank;between outputs ± 1.5 % (max) : S rank;between devices: ± 1.5 % (max) : N rank;between outputs ± 2.5 % (max) : N rank;between devices: ± 2.5 % (max) • Output voltage : VOUT = 17 V (max) • High-speed output switching : twOE = 25 ns (min), tor = 10ns (typ.), tof = 10ns (typ.) There is TC62D748 as an output switching standard-speed version of this product. • I/O interface : CMOS interfaces (Schmitt trigger input) • Data transfer frequency : fSCK = 25 MHz (max) • Operation temperature range : Topr = −40 to 85 °C • Power-on-reset function built-in. (When the power supply is turned on, internal data is reset) • Package : P-SSOP24-0409-0.64-001 For detailed part naming conventions, contact your local Toshiba sales representative or distributor. When the LED driver of high-speed output switching is used, back EMF may occur at the time of output OFF, and output terminal voltage may rise. Please be careful. It is necessary to reduce inductance to prevent the back EMF. It is possible to reduce inductance of a substrate by making the power supply for LED wiring shorter and wider designing the layout pattern. P-SSOP24-0409-0.64-001 Weight: 0.14 g (Typ.) |
