Each channel has adjustable 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, selectable oscillator source for PWM function, 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 12-bit 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 (~4.
4KHz) with internal oscillator (~ 18 MHz)) z Build-in real-time LED open detection z Package and pin assignment (except QFN32) compatible to pure LED drivers 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) 16-channel 12-bit PWM Constant Current LED Driver Version:A.
