TC62D776CFNAG TOSHIBA CDMOS Integrated Circuit Silicon Monolithic TC62D776CFNAG 16-Channel Constant-Current LED Driver of the 3.3-V and 5-V Power Supply The TC62D776CFNAG 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 TC62D776CFNAG 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 TC62D776CFNAG allows P-SSOP24-0409-0.64-001 high-speed data transfer. Weight : 0.14g (typ.) It operates with a 3.3- or 5-V power supply Features Supply voltage : V = 3.0 to 5.5 V DD 16-output built-in Output current setup range : IOUT = 1.5 to 90 mA Constant current output accuracy ( REXT = 1.2 k , 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) = 17 V (max) Output voltage : VOUT I/O interface : CMOS interfaces (Schmitt trigger input) Data transfer frequency : f = 25 MHz (max) SCK Operation temperature range : T = 40 to 85 C opr 8-bit (256 steps) current correction function built-in. 1 bit (HC) by the MSB side: Selects the output current range. 7 bit by the LSB side: Output current is adjusted at 128 steps in the range of 11% to 45%. (In the case of HC=1) Output current is adjusted at 128 steps in the range of 50% to 200%. (In the case of HC=0) Thermal shutdown function (TSD) built-in. Output error detection function built-in. Auto-output error detection and manual-output error detection using commands Output open detection function (OOD) and output short detection function (OSD) built-in. Power-on-reset function built-in. (When the power supply is turned on, internal data is reset) Stand-by function built-in. (IDD = 1 A at standby mode) Output delay function built-in. (Output switching noise is reduced) Package : P-SSOP24-0409-0.64-001 For detailed part naming conventions, contact your local Toshiba sales representative or distributor. 1 2014-10-01 2014 TOSHIBA Corporation TC62D776CFNAG Block Diagram OUT0 OUT1 OUT15 Error detection result data Error detection circuit register Reference TSD voltage circuit circuit Constant current output circuit R-EXT Output delay circuit 8bit DAC ENABLE State setting ON/OFF data register register 16 16 Command TRANS control Data transfer control circuit circuit 16 16 SOUT selection SIN 16-bit shift registor SOUT circuit F/F VDD POR SCK circuit GND Pin Assignment (top view) GND VDD SIN R-EXT SCK SOUT TRANS ENABLE OUT0 OUT15 OUT1 OUT14 OUT2 OUT13 OUT3 OUT12 OUT4 OUT11 OUT5 OUT10 OUT6 OUT9 OUT7 OUT8 2 2014-10-01
