First,
DM13A chip core technology highlights
16-bit high-precision constant current: Independent 16-bit DAC per channel, output current range 5mA-90mA (±1.5% accuracy), supporting delicate color transition of full-color leds.
Intelligent dimming control:
PWM gray adjustment: 1MHz high frequency PWM dimming, eliminating the human eye can detect ststrobe, refresh rate up to 4000Hz.
Dynamic Energy saving mode: Static current as low as 0.1μA, standby power consumption is reduced by 70%.
Anti-interference design: Built-in ESD protection (±8kV) and synchronous noise reduction circuit to ensure signal stability in complex electromagnetic environment.
2. Typical application scenarios and cases
LED display:
Drive Mini LED backlight module to achieve HDR 10+ display standard with 1,000,000:1 contrast ratio.
Case: A brand of 4K advertising screen, using
DM13A chipset, the whole screen brightness uniformity > 98%, power consumption reduced by 25%.
Intelligent lighting system:
Support DMX512, SPI dual protocols, used for building facade dynamic light show, 256 level scene seamless switching.
Car lighting:
Withstand -40℃~105℃ temperature range, drive car atmosphere light, through AEC-Q100 vehicle certification.
3. Key points of hardware design
Circuit layout optimization:
Star grounding design, PCB wire width ≥0.3mm to reduce impedance.
It is recommended to parallel 104 ceramic capacitors per channel to suppress current ripple (ripple coefficient < 3%).
Heat management:
The bare pad at the bottom of the chip (EPAD) should be connected with a large area of copper foil (≥10mm²), and the junction temperature should be controlled within 85 ° C.
When multiple chips are cascaded, ensure that the spacing is at least 5mm to ensure air circulation.
4, dimming configuration and protocol compatibility
Grayscale data interface:
Supports 16-bit SPI serial input (clock rate 20MHz) with no data delay in cascading mode.
Hardware-grade Gamma calibration table for sRGB/DCI-P3 color gamut standard.
Dimming mode switch:
Select PWM/ analog dimming via pin configuration and support external PWM signal synchronization (duty cycle resolution 0.1%).
5. Fault diagnosis and maintenance
Intelligent protection mechanism:
Overtemperature protection (OTP) : Automatically turn off the output when the junction temperature is more than 150℃, and recover after cooling.
Open/short circuit detection: Real-time feedback on faulty channel STATUS (error code output via STATUS pin).
EMC optimization solution:
It is recommended to add a common-mode inductor (100μH) and TVS diode at the power input, and pass FCC Class B certification.
