产品概述
描述
The L9949 is a microprocessor controlled power interface for automotive applications. It is realized in multipower BCD60III technology. Up to three DC motors 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.
