Analog Dimming
The PWM duty cycle is controlled by analog voltage which is the output of the brightness control
volume on a dashboard. The dimming curve is mask-programmable with the following
limitations;
1. Maximum duty cycle is 12.5%.
12.5%
Max 12.5%
100% (DUTY)
512kHz
DUTY CYCLE STEP
2. Number of pulse stops is max. 52.
3. Input Voltage to "VD"
The input voltage to "VD" needs to use a voltage divider as shown below.
VD-IN
VD
2R
R
Note:
The maximum voltage to the VD is 5V.
4. Maximum Threshold Voltage
The maximum threshold voltage is 5.0V.
5. Minimum & Maximum VDIM Input Voltage
The minimum threshold voltage step is 20mV.
Only for the first step, the threshold voltage can be any value between 20mV and 3V.
