TB62D786FTG TOSHIBA BiCD Process Integrated Circuit Silicon Monolithic TB62D786FTG 9-channel constant current LED driver with single wire The TB62D786FTG is a constant current driver designed for LED TB62D786FTG illumination. This product incorporates 7-bit PWM dimming controllers and 9-channel constant current drivers. 9-channel constant current drivers are divided into three blocks corresponding to LED luminescence colors, and each output current can be adjusted by external resistors. This product is controlled using the only DATA-IN input signal. It can be configured up to 64 recognition addresses with the ID setting pin. This product includes a linear regulator (7.0 to 28 V) function, which P-VQFN24-0404-0.50-001 shares with the power supply of LEDs. Weight: 0.037g (typ.) Additionally, data can be transferred at high speed with BiCD process. Feature Power supply voltage : VL = 7.0 to 28 V (The case used by sharing with a power supply of LED) Vcc = 5.0 V10% (The case that the power supply of LED and that of this IC separately. ) Maximum output current capability:80 mA (max) 9 channels Constant current output range: 5 to 40 mA Output voltage at constant-current drive: 0.4 V(min) I =5 to 40 mA OUT Designed for common-anode LEDs. The input interface is controlled by DATA-IN (Single wire) Thermal shut down (TSD) included. Input and output of logic circuit: 5 V CMOS Interface Maximum output voltage: 28 V PWM control circuit included: 7-bit PWM Driver recognition: Up to 64 driver ICs can be controlled individually Operating temperature range: T = -40 to 85C opr Package: P-VQFN24-0404-0.50-001 Constant current accuracy Constant-current accuracy Constant-current accuracy Condition between channels between ICs Output voltage: 0.5 V 3.0% 6.0% Output current: 15 mA This product is very delicate because of elements of MOS structure. In handling, please take care of measures of static electricity, such as use of a ground band or an electric conduction mat, removal of static electricity by an ionizer, and management of temperature and humidity. 2016-2018 1 2018-08-02 Toshiba Electronic Devices & Storage Corporation TB62D786FTG Pin Assignment (top view) VLOUT 19 12 ID0 NC 20 11 GND 21 10 REXT-B VL TOP VIEW /OUTR0 REXT-G 22 9 /OUTG0 23 8 REXT-R 24 7 PGND /OUTB0 Please be sure to connect the back radiation PAD of a QFN package to GND of a substrate.
