Description
AI
The DAC539G2-Q1 is an application-specific, look-up table (LUT) based GPI-to-PWM converter. This device has a 10-bit GPI-to-voltage output converter and a voltage-to-PWM converter. Both these circuits can be externally connected to create a GPI-to-PWM converter. Three GPIs are mapped to eight 10-bit digital codes that represent the voltage output. There is a programmable delay at the GPIs for eliminating glitches on these inputs. The look-up table values are programmed using I 2C or SPI and stored in the NVM. The GPIs are multiplexed with the I 2C and SPI. The voltage-to-PWM converter uses a comparator with one input as a programmable sawtooth or triangle waveform and the other input as an external voltage input.
This device automatically detects I 2C and SPI and has an internal reference. The DAC539G2-Q1 is an excellent choice for fault communication in automotive stop and turn lights and similar industrial applications.
