TC62D776CFG
TC62D776CFG
16-Channel Constant-Current LED Driver of the 3.3-V and 5-V Power Supply
The TC62D776CFG 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 TC62D776CFG 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 TC62D776CFG allows
high-speed data transfer.
It operates with a 3.3- or 5-V power supply.

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 = 1μA at standby mode)
Output delay function built-in. (Output switching noise is reduced)
