The TLC5958RTQR from Texas Instruments is a versatile 48-channel LED driver designed for applications requiring precise brightness control. It utilizes 16-bit Enhanced Spectrum Pulse Width Modulation (ES-PWM) for grayscale control, offering 512 analog dimming steps per color group.
This linear LED driver supports a constant current sink output with a capability of up to 25mA at 5VCC and 20mA at 3.3VCC. Key features include LED open detection (LOD), thermal shutdown (TSD), and IREF resistor short protection (ISP). The device operates with a Vcc range of 3.0V to 5.5V and can drive LEDs with a power supply voltage up to 10V.
Packaged in a 56-VFQFN (8x8 mm) with exposed pad, the TLC5958RTQR is suitable for surface mount applications. Its design incorporates a pre-charge FET to prevent ghosting and delay switching to avoid inrush current. The operating temperature range is -40°C to 85°C, making it robust for various environmental conditions. The device also supports 32-multiplexing and includes 48K bit of grayscale data memory.
Ideal for signage and display applications, the TLC5958RTQR provides high accuracy with channel-to-channel variation typically ±1% and device-to-device variation typically ±1%. The data transfer rate is up to 25MHz, and the grayscale clock runs at 33MHz.
