RS3703-Q1 RS3703-Q1 Three-Channel High-Side LED Driver with Thermal Sharing and Off-Board Binning 1 FEATURES 3 DESCRIPTIONS  RS3703-Q1 AEC-Q100 Qualification is The RS3703-Q1 three-channel LED driver includes an unique thermal management design to reduce Ongoing  Wide Input Voltage Range: 4.5 V to 40 V temperature rising on the device. The RS3703-Q1 is  Thermal Sharing by External Shunt Resistor a linear driver to output full current loads up to 150  Low Supply Current in Fault Mode mA per channel. External shunt resistors are  Three High-Precision Current Regulation: leveraged to share output current and dissipate power out of the driver. The RS3703-Q1 also drives - Up to 150mA Current Output for Each LED units and off-board brightness binning resistors Channel - ±5% Accuracy Over Full Temperature Range to simplify the manufacturing process and lower - Independent Current Setting by Resistor whole system cost. Its full-diagnostic capabilities - Independent PWM Pin for Brightness Control include LED open, LED short-to-GND circuit and - Support Off-Board Brightness Binning single LED short circuit detection. Resistor Device Information (1) - Support External NTC for Current Derating  Low Dropout Voltage: PART NUMBER PACKAGE BODY SIZE (NOM) RS3703-Q1 ETSSOP20 6.50mm×4.40mm - TYP Dropout: 315 mV at 150 mA (1)  Diagnostics and Protection - LED Open-Circuit with Auto-Recovery For all available packages, see the orderable addendum at the end of the data sheet. - LED Short-to-GND with Auto-Recovery - Single LED Short-Circuit Detection with 4.5V to 40V RS3703-Q1 SUPPLY Auto-Recovery C(SUPPLY) - Diagnostic Enable with Adjustable Threshold - Fault Bus Configurable as either One-Fails– R (SNS1) R (SNS2) R (SNS3) All-Fail or Only-Failed-Channel Off (N-1) EN OUT1 IN1 RES2 IN2 OUT2 IN3 RES3 DIAGEN - Thermal Shutdown PWM1  Operation Junction Temperature Range: –40°C to 150°C RES1 OUT3 R (RES1) C(OUT1) R (RES2) C(OUT2) R (RES3) C(OUT3) PWM2 IREF PWM3 SLS_REF FAULT ICTRL R (ICTRL2) C(IREF) GND R (IREF) LED Board R (SLS_REF) R (ICTRL1) C(ICTRL) Typical Application Diagram 2 APPLICATIONS  General-Purpose LED Driver Applications REV A.0 1 / 36 www.run-ic.com PDF
