General Description

BD9397EFV is a high efficiency driver for white LEDs and designed for large LCD panel.

This IC is built-in high current drive and high responsibility type 6ch LED drivers and 1ch boost DCDC converter.

BD9397EFV has some protect function against fault conditions, such as the over-voltage protection (OVP), LED OPEN and SHORT protection, the over current limit protection of DCDC (OCP).

Key Features

  • 6ch Constant LED drivers, available 400mA drive per 1ch.
  • Constant current accuracy ±1.8% (IC only).
  • Each 6ch external PWM inputs can control independent dimming.
  • Current analog (linear) dimming by VREF.
  • 1ch boost controller with current mode (external FET).
  • Several protection functions DCDC part : OCP/OVP/UVLO/TSD LED driver part :OPEN,SHORT detection.
  • SHORT detection voltage is set by LSP terminal.
  • Error detection output FAIL terminal inside.
