Description

This Linear LED driver is designed to meet the stringent requirements of automotive applications. The BCR430U is a monolithically integrated linear LED controller
designed to function as a Constant Current Regulator (CCR) for linear LED driving. The device operates over a voltage range from 5V to 42V and regulates the output LED current up to 100mA, set by an external resistor. It is designed for driving LEDs in strings and will reduce current at increasing temperatures to self-protect. The low
voltage drop during current regulation allows efficient driving of LED strings with a range of forward voltages and supply voltage tolerances

Feature(s)

  • LED Current Tolerance of ±5% at 95mA Output Current
  • Thermal Protection Reduces LED Current at Elevated
    Temperature
  • Low Typical Saturation Voltage of 115mV at 50mA
  • 5mA to 100mA Adjustable LED Current with an External Resistor
  • 5V to 42V Supply Voltage
  • High Power 1W Dissipation in SOT26
  • No External Capacitor is Required for Stable Operation
  • LED Dimming Using PWM
  • Parallel Devices to Increase Regulated Current
  • Totally Lead-Free & Fully RoHS Compliant
  • Halogen and Antimony Free. “Green” Device 
  • The BCR430U is suitable for automotive applications
    requiring specific change control; this part is AEC-Q100
    qualified, PPAP capable, and manufactured in IATF16949
    certified facilities.
