 Low RDSON SPI controlled H-Bridge

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 circuit to ground, short circuit overload, over temperature.

Features

• 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
