TB62781FNG

TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic

TB62781FNG

9-Channel Constant-Current LED Driver of the 3.3-V and 5-V Power Supply Voltage Operation

The TB62781FNG is a constant-current driver designed for LED

and LED display lighting.

This product incorporates 7-bit PWM dimming controllers and 9

channels of constant-current drivers. 9 constant-current drivers

are divided into three blocks, and each block can be

independently adjusted by the relevant external resistor.

This IC is controlled using the SDA and SCLK input signals, and

capable of high-speed data transfers.

SSOP20-P-225-0.65A

Weight: 0.10 g (typ.)

This product can be set addresses with ID setting pins. (Up to 64

addresses can be controlled independently.)

High-speed transferring is capable by applying Bi-CMOS process.

This product operates with a supply voltage of 3.3 V or 5 V.
