Preliminary Datasheet 1.0 Block Diagram Figure 1: INLC10AQ block diagram
The device implements a communication for the reception of control commands and for providing device status and configuration data. Low side, configurable constant current sinks are provided for controlling 3 LEDs (i.g. RGB). The main unit computes the PWM duty cycles from the incoming commands and applies the corresponding control values to the three PWM units. The main unit is also in charge of a periodic temperature measurement and an appropriate duty cycle adjustment for the red PWM channel. The actual device temperature is obtained via an integrated analog-digital converter (ADC). Besides the temperature the ADC can also measure various other analog values. These measurements are always triggered by a command from the host. The result of the corresponding A/D conversion is also retrieved by a host command. As each device is individually calibrated to compensate for production variations, the corresponding parameters can be stored in an on-die non-volatile memory. This one-time-programmable memory (OTP) is read at hardware reset and the parameters are copied from the OTP to directly accessible registers.
