Visão Geral
Description
The SN3236I544E is a 16-channel LED driver IC designed for driving LEDs with constant current. It features 16-bit shift registers, data latches, and constant current output circuits, making it suitable for LED displays, signage, and lighting applications.
Key features:
- 16 constant current outputs (adjustable via external resistor)
- 3.3V to 5V supply voltage
- 30MHz high-speed data transfer
- Low standby current
- Thermal shutdown protection
The IC supports cascading for driving multiple LEDs in series and includes PWM brightness control for dynamic lighting effects. Its compact design and efficient performance make it ideal for space-constrained applications.
For detailed specifications, refer to the datasheet from the manufacturer (e.g., Texas Instruments or other vendors).
