Description
MAX8969EWL50+T is Maxim Integrated’s multi‑channel LED driver and power‑management IC. The EWL50+T suffix denotes a 50‑pin wafer‑level package (EWL) in tape‑and‑reel form. The device provides multiple current‑regulated LED outputs with programmable current per channel, supports dimming (PWM/analog), and includes protective features (fault reporting, short/open LED protection, overtemperature/UVLO). It also integrates power management to efficiently drive LEDs from a higher input voltage. Control is via a serial interface to set channel currents, dimming, and fault status. Applications include LED backlighting for displays, automotive lighting, architectural lighting, and signage. For exact channel count, current ranges, input voltage limits, and interface details, consult the MAX8969 datasheet and the EWL50+T package data.
Features
MAX8969EWL50+T is a Maxim multi-channel LED driver/power-management IC in an eWLP50 package. Key features:
- I2C-compatible control interface for programming and status readback
- Multi-channel high-side current sinks with individually adjustable currents
- PWM and analog dimming support
- Robust protection: LED open/short fault protection, overcurrent, overtemperature, undervoltage lockout
- Wide input voltage range suitable for automotive/battery applications with high efficiency
- Fault/status reporting via registers and status pins
- Small, thermally efficient eWLP50 package (RoHS-compliant)
Note: for exact channel count, current ranges, and electrical specs, consult the latest datasheet.
