The MY9291QD is a versatile 4 or 3-channel constant current LED driver IC manufactured by MY-Semi Inc. It is designed for applications requiring precise LED current control, operating within a 3V to 5.5V supply voltage range. The device offers selectable output channels, supporting configurations like R/G/B/W or R/G/B/Amber.
Each of the 4 or 3 open-drain constant current sinking outputs is rated to 17V and can deliver up to 350mA. The current is programmable via four external resistors, allowing for flexibility in design. The MY9291QD features a 2-wire serial interface for grayscale data and control commands, including 16/14/12/8-bit grayscale selection. It utilizes Adaptive Pulse Density Modulation (APDM) to achieve high visual refresh rates (up to 2000 Hz at 16-bit grayscale) and reduce flicker.
This LED driver is available in QFN20, SSOP20, and TSSOP20 (Exposed Pad) packages. It is specified for operation over an ambient temperature range of -40°C to +85°C, making it suitable for various indoor and outdoor LED display and lighting applications.
Key features include ±1.5% typical channel-to-channel LED current accuracy and a 10MHz EMI reduction data clock input. The device also supports clock duty recovery for cascading applications and programmable output current rise/fall times.
