MIC5400
Overview
The MIC5400 consists of 2 banks of 8 LED driver outputs, each output capable of sinking up to 30mA. Each bank is intended to drive 8 LED pixels of the same color.
- 2 banks of 8 outputs
- Output characteristics:
- Current sink: 30mA - Programmable brightness control
- Coarse: 4-bit resolution DAC
- Fine: 10-bit resolution PWM - Resistor sets maximum LED current to compensate variation in LEDs - Current limit on each output
- Full protection: - Over-temperature shutdown - Watchdog disables output under fault condition - Power-on reset (all LEDs Off) - Soft-start on power up and watchdog recovery - Output open fault detection with status register readback
- Output transitions are staggered to minimize supply transients
