Preliminary Datasheet
16-Channel Constant Current LED Driver
With 16-bit PWM Control and Dot-Correction
Features
16 constant-current output channels
Constant output current range per channel: 2~60mA
Small Outline Package
2~60mA @ 5V supply voltage
2~45mA @ 3.3V supply voltage
Excellent output current accuracy,
- Between channels: <±1.5% (typ.);
- Between ICs: <±3% (typ.)
Visual effect control
GF: SOP24-300-1.00
- Patented S-PWM technology to improve refresh rate
- 16-bit or 12-bit gray scale control
- 8-bit dot-correction
Thin Shrink SOP
- 7-bit linear programmable output current gain
Error detection control
- In-message error detection:
on-the-fly, data-in error-out
- Compulsory individual LED open/short-circuit detection:
full panel, data independent
GTS: TSSOP24-173-0.65
silent error detection in 700ns
- Configurable short-circuit detection threshold voltage
QFN
- Thermal protection
Flexible operation modes
- Auto synchronization mode/manual synchronization mode
- One-shot mode/continuous mode
- Disable/enable command
GFN: QFN24-4*4-0.5
EMI reduction
- Staggered delay of output, preventing from current surge
- Selectable switching speed of output channels (tOR, tOF)
Maximum data clock frequency: 30MHz
Maximum gray scale clock frequency: 33MHz
Schmitt trigger input
Backward compatible with MBI5026 and MBI5030 in package
Application
Full-color LED display
