Product details

Description

The RT8491 is a 6-CH LED driver controller that delivers well matched LED current to each channel of LED string.

With external current sources, the number of LEDs per string is only limited by the current source and the VIN/ VOUT conditions.

Features

Wide Operation Voltage Range : 9V to 32V.
Programmable Channel Current.
3% Current Matching Accuracy between Channels.
Programmable Switching Frequency.
Easy Analog and Digital Dimming Control.
Programmable Soft-Start.
LED Open Channel Detection and Protection.
LED Short-Fault Detect Latch Off Multiple LED Strings.
Programmable Output Over Voltage Protection.
Under Voltage Lockout and Thermal Shutdown.
32-Lead WQFN Package.
