DM632C
16-CHANNEL CONSTANT CURRENT LED DRIVER
WITH PROGRAMMABLE PWM OUTPUTS
General Description
DM632C is a 16-channel constant current sink LED driver. Each channel has adjustable 16-bits
(65536 steps) grayscale PWM control current outputs. It incorporates shift registers, data latches,
constant current circuitry with current value set by an external resistor, selectable oscillator source
for PWM functioning, and built-in LED open detection circuit to detect error status. It is specifically
designed for LED display or lighting applications.
Features
z Constant-current outputs: 5mA to 90mA adjustable by one external resistor
z 16-bit linear PWM control current outputs for each channel
z Maximum output voltage: 17V
z Maximum clock frequency: 25MHz
z Selectable internal/external PWM reference clock
z PWM free-running capability (refresh rate (~ 275Hz) with internal oscillator (~ 18 MHz))
z Build-in real-time open detection
z Package and pin assignment (except QFN32) compatible to pure LED driver series
(ST2221C, DM134/5/6, DM13C)
z Power supply voltage: 3.3V to 5.5V
Applications
z Indoor/Outdoor LED Video Display
z LED Variable Message Signs (VMS) System
z LED Decorative Lighting
Package Types
z SOP24, SOP24B, SSOP24, TSSOP24E (with exposed pad), QFN32 (with exposed pad)
