L9958 - STMicroelectronics

L9958 Low RDSON SPI controlled H-Bridge

The L9958 is an SPI controlled H-Bridge, designed for the control of DC and stepper motors in safety critical applications and under extreme environmental conditions. Datasheet - production data The H-Bridge is protected against over temperature, short circuits and has an undervoltage lockout for all the supply voltages Vs and Vdd, and for overvoltage on V.
