L9958 - Low RDSON SPI controlled H-Bridge

📥 Download Datasheet

General Description

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 Vdd.

All malfunctions cause the output stages to go tristate.
