Description
General part information
L9374 Series
The L9374LF is a SPI (serial peripheral interface) controlled four channel low side driver with integrated recirculation diodes.
The output duty cycle (all channels) / current regulation level (Q3 & Q4 only) can be programmed individually. It is possible to program two consecutive output duty cycles or target currents per channel as well as an individual duration time for each channel actuation.
