AL5873Q 55V/250mA THREE-CHANNEL LINEAR LED DRIVER Description Pin Assignments
The AL5873Q is an automotive-grade three-channel linear LED Top View driver with PWM dimming and analog dimming control. Each channel can drive up to 250mA with a total driving current up to 750mA. The VIN 1 16 FAULTB
N
LED channel current of the AL5873Q can be set by two reference NC 2 15 ADIM resistors connected to the REF1 and REF2 pin.
IO
PWM 3 14 REF1
T A
The AL5873Q regulates LED current for each channel, accurate NC 4 13 FULL
M
down to ±4%, with excellent dimming performance. The AL5873Q EP
R
enters standby mode to save power if no PWM signal is detected. NC 5 12 REF2
O
GND 6 11 LED1
F
The AL5873Q monitors the temperature and reduces the LED current if the chip temperature exceeds the threshold temperature. And the GND 7 10 LED2
IN
input under voltage lock-out (UVLO), LED string open / short
D
GND 8 9 LED3
E
protection, over temperature protection (OTP), and fault indicator
C
(FAULTB) are designed for automotive applications to improve
N
TSSOP-16EP (Type DX) system robustness.
A V
The AL5873Q is available in TSSOP-16EP (Type DX) package.
D A Applications Features
Automotive LED Inner Lamps AEC-Q100 Grade 1 Qualification Rear Light – Tail and Stop Light, Rear Turn Indicator, Parking Wide Input Voltage Range from 5V to 55V Light, Fog Light, Reverse Light Each Channel Up to 250mA Current Capability Set Stop and Tail Current Independently Through 2 Resistors Switch LED Current Between Stop and Tail Function Automatically via FULL Input PWM Dimming via Both PWM Input and Power Supply Analog Dimming via ADIM Input Automatically Enter and Exit Standby Mode without Enable Pin Internal Protections: Input Under Voltage Lock-Out (UVLO) LED String Open Protection LED String Short Protection Over Temperature Protection (OTP) Thermal Fold-back if Chip Temperature Exceeds the Threshold Fault Reporting: UVLO, OTP, LED Open, and LED Short
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) The AL5873Q is suitable for automotive applications requiring specific change control; this part is AEC-Q100 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. https://www.diodes.com/quality/product-definitions/
Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.
