Datasheet Constant Current LED Drivers Constant Current Controller for Automotive LED Lamps BD18345EFV-M General Description BD18345EFV-M is 70 V-withstanding constant current controller for automotive LED lamps. It is able to drive at maximum 10 rows of PNP transistors. It can also contribute to reduction in the consumption power of the set as it has the built-in standby function. The IC provides high reliability because it has two Current de-rating function, LED open detection, short circui.

Datasheet Constant Current LED Drivers Constant Current Controller for Automotive LED Lamps BD18345EFV-M General Description BD18345EFV-M is 70 V-withstanding constant current controller for automotive LED lamps. It is able to drive at maximum 10 rows of PNP transistors. It can also contribute to reduction in the consumption power of the set as it has the built-in standby function. The IC provides high reliability because it has two Current de-rating function, LED open detection, short circuit protection, over voltage mute function and LED failure input/output function. Features  AEC-Q100 Qualified(Note 1)  PWM Dimming Function  PWM Signal Output  LED Current DC Dimming  Thermal De-rating Function  LED Open Detection  Short Circuit Protection (SCP)  Over Voltage Mute Function (OVM)  Disable LED Open Detection Function at Reduced-Voltage  LED Failure Input/Output Functions (PBUS) (Note 1) Grade1 Key Specifications  Input Voltage Range:  FB Pin Voltage Accuracy: 4.5 V to 19.0 V 650 mV ±3 % @Ta=25 °C to 125 °C  Stand-by Current:  LED Current De-rating Accuracy: 0 µA (Typ) DCDIM Pin : ±3 % @VDCDIM=0.75 V to 2.00 V THD Pin : ±6 % @VTHD=0.50 V to 0.75 V  Operating Temperature Range: -40 °C to +125 °C Package HTSSOP-B20 W (Typ) x D (Typ) x H (Max) 6.50 mm x 6.40 mm x 1.00 mm HTSSOP-B20 Applications  Automotive LED Exterior Lamp (Rear Lamp, Turn Lamp, DRL/Position Lamp, Fog Lamp etc.)  Automotive LED Interior Lamp (Air Conditioner Lamp, Interior Lamp, .
