Overview

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.

  • Programmable current regulation peak threshold by SPI up to 8.6 A typ.
  • Operating battery supply voltage 4.0 V to 28 V
  • Operating Vdd supply voltage 4.5 V to 5.5 V
  • All pins withstand 19 V, Vs and output pins withstand 40 V
  • Full path Ron from 100 mΩ (at Tj = -40 °C) to 300 mΩ (at Tj =150 °C)
  • Logic inputs TTL/CMOS-compatible
  • Operating frequency up to 20 kHz
  • 16-bit SPI interface for configuration/diagnostics, daisy chain capability
  • Over temperature and short circuit protection
  • VS undervoltage disable function
