Product overview
Description
The L9848 IC is a highly flexible monolithic medium current output driver that incorporates 2 dedicated low side outputs (outputs 7-8) and 6 outputs that can be used as either internal low or high side drives in any combination (outputs 1-6).
In addition, 2 outputs are capable of being PWMed via an external pin (outputs 5-6). The integrated standard serial peripheral interface (SPI) controls all outputs and provides diagnostic information.
Integrated clamping circuits, waveshaping, protection against positive and negative voltage transients and thermal shutdown for all outputs open a wide range of automotive and industrial applications
-
