(continued) tors and one grounded resistive load can be driven with its three half bridges, one full bridge and one highside driver power outputs. The integrated standard serial peripheral interface (SPI) controls all operation modes (forward, reverse, brake and high impedance). All diagnostic informations are available via the SPI. Dual Power Supply: VS and VCC The power supply voltage VS supplies the full bridge, the half bridges and the highside driver.
