Introduction

AI Translation

HTM1740 is a constant-current LED display driver control IC featuring strong drive capability, with an integrated MCU digital serial interface, data memory, and LED constant-current control driver module. Manufactured using CMOS process technology, it is primarily designed for high-brightness small-to-medium-sized LED display driving applications. HTM1740 is a constant-current driver IC based on the I2C communication protocol for LED display panel designs, supporting up to 8-segment × 16-digit output. The number of scan digits can be configured via registers to achieve higher per-point drive current. Compared to conventional LED display panel driver ICs — where the current through individual LEDs fluctuates as the number of illuminated LEDs or the input voltage changes, thereby affecting display brightness — HTM1740's constant-current design ensures that once the display mode is configured, the current through each LED remains constant and does not vary with changes in the number of illuminated LEDs or input voltage.
