支持独立调光的四通道汽车 LED 控制器

A80804

A80804 提供灵活的汽车 LED 照明控制，具有四路独立可调光通道，支持内部与外部 PWM 选项及模拟调光，实现精确亮度控制。

Internal and external PWM dimming options
Two ADIM pins for LED binning, NTC feedback, or hybrid analog/PWM dimming
Adjustable integrated LED current derating for elevated VIN
Integrated LED current derating for elevated IC junction temperature
MINOUT signal for trimming pre-regulator to minimize power loss
Selectable LED current slew rate limit during PWM dimming
Extensive fault detection and protection
Current sense voltage options of 500mV (A80804) for better BCI immunity or 200mV (A80804-1) for lower power dissipation in the sense resistors
