独立調光対応4チャネル車載LEDコントローラ

A80804

A80804は、独立調光可能な4つのチャネル、内部および外部PWMオプション、正確な輝度制御を可能にするアナログ調光の機能を搭載し、車載LED照明を柔軟に制御します。

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
