16-channel linear LED driver for automotive backlighting
The NXP PCA9952TW/Q900,118 is a 16-channel linear LED driver with constant-current sinks rated at 57 mA per channel, targeting backlight applications in automotive-grade systems. Each output integrates an internal switch, so no external driver FETs are needed for the constant-current path — the 40 V output compliance handles series LED strings typical in dashboard and infotainment backlights.
PWM dimming and supply range
Dimming is controlled via PWM on each channel independently, allowing per-LED brightness adjustment without analog current scaling.
