HTR3229 - 16x8 MATRIX LED DRIVER

General Description

LED Matrix programmed via 1MHz I2C compatible interface.

Each LED can be dimmed individually with 8-bit PWM data, and each CSx has 8-bit DC scaling (Color Calibration) data which allowing 256 steps of linear PWM dimming for each dot and 256 steps of DC current adjustable level for each CSx.

Key Features

  • S Supply voltage range: 2.5V to 5.5V 16 current sinks Support 16×n (n=1~8), 15×9 LED matrix configurations Individual 256 PWM control steps 256 DC current steps for each CSx 64 global current steps SDB rising edge reset I2C module 32kHz PWM frequency 1MHz I2C-compatible interface Individual open and short error detect function PWM 180 degree phase shift Spread Spectrum De-Ghost QFN-32 (4mm×4mm) package.
