16-CHANNEL CONSTANT CURRENT LED DRIVER
WITH 12-bit PROGRAMMABLE PWM OUTPUTS
General Description
DM631B is a 16-channel constant current sink LED driver. Each channel has independent
12-bits (4096 steps) grayscale PWM control current outputs. It incorporates shift registers, data
latches, constant current circuitry with current value set by an external resistor, and built-in LED
open detection circuit to detect error status. It combines the selections with rising / falling edge
serial out, auto-reload/one-shot PWM output, internal/external grayscale clock source. It is
specifically designed for LED display or lighting applications.
Features
z Constant-current outputs: 5mA to 60mA adjustable by one external resistor
z 12-bit linear PWM control current outputs for each channel
z Maximum output voltage: 17V
z Maximum clock frequency: 25MHz
z Auto-Reload / One-Shot Mode selection.
z Serial out clock edge selection – Rising / Falling edge selection
z Internal / External PWM clock mode selection
z Built-in real-time open detection
z Package and pin assignment compatible to conventional LED drivers
(DM134/5/6, DM13C)
z Power supply voltage: 3.3V to 5V
z Schmitt Trigger input
z Output channel delay
Applications
z Indoor/Outdoor LED Video Display
z LED Variable Message Signs (VMS) System
z LED Decorative Lighting
Package Types
z DIP24B, SOP24B, SSOP24, TSSOP24E (with exposed pad)
