Datasheet Diodes AL5873Q
Automotive Three-Channel Linear LED DriverThe AL5873Q is an automotive-compliant three-channel linear LED driver with PWM dimming and analog dimming control.
Automotive Three-Channel Linear LED DriverThe AL5873Q is an automotive-compliant three-channel linear LED driver with PWM dimming and analog dimming control
Each channel can drive up to 250mA with a combined driving current up to 750mA. All three LED channels’ current of the AL5873Q are set by two reference resistors connected to the REF1 and REF2 pin. The AL5873Q regulates LED current for each channel, accurate down to ±4%, with excellent dimming performance. The AL5873Q enters standby mode to save power if no PWM signal is detected.The AL5873Q monitors the temperature and reduces the LED current if its juncture temperature exceeds the threshold temperature. For improved system robustness the AL5783Q has input under voltage lock-out (UVLO), LED string-open /-short protection, and overtemperature protection (OTP) which are reported by a fault indicator (FAULTB) pin. The AL5873Q is available in TSSOP-16EP (Type DX) package.
