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.
