BD9397EFV-E2规格书详情
●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). Therefore BD9397EFV is available for the fail-safe design over a wide range output voltage.
●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 (normal=Open, error=Drain)
●Key Specification
Operating power supply voltage range: 9.0V to 35.0V
Oscillator frequency: 500kHz (RT=30kΩ)
Operating Current: 9mA (typ.)
Operating temperature range: -40°C to +85°C
