Description for the DRV8718-Q1

The DRV871x-Q1 family of devices are highly integrated, multi-channel gate drivers intended for driving multiple motors or loads. The devices integrate either 4 (DRV8714-Q1) or 8 (DRV8718-Q1) half-bridge gate drivers, driver power supplies, current shunt amplifiers, and protection monitors reducing total system complexity, size, and cost.

A smart gate drive architecture manages dead time to prevent shoot-through, controls slew rate to decrease electromagnetic interference (EMI), and optimizes propagation delay for optimal performance.

Input modes are provided for independent half-bridge or H-bridge control. Four PWM inputs can be multiplexed between the different drivers in combination with SPI control.

Wide common mode shunt amplifiers provide inline current sensing to continuously measure motor current even during recirculating windows. The amplifier can be used in low-side or high-side sense configurations if inline sensing is not required.

The devices provide an array of protection features to ensure robust system operation. These include under and overvoltage monitors, VDS overcurrent and VGS gate fault monitors for the external MOSFETs, offline open load and short circuit diagnostics, and internal thermal warning and shutdown protection.
