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. Detailed failure diagnostics on each channel is provided via SPI: short circuit to battery, short ...
