Beschreibung
The DRV8705-Q1 is a highly integrated H-bridge gate driver, capable of driving high-side and low-side N-channel power MOSFETs. It generates the proper gate drive voltages using an integrated doubler charge pump for the high-side and a linear regulator for the low-side.The device uses a smart gate drive architecture to reduce system cost and improve reliability. The gate driver optimizes dead time to avoid shoot-through conditions, provides control to decreasing electromagnetic interference (EMI) through adjustable gate drive current, and protects against drain to source and gate short conditions with VDS and VGS monitors.A low-side shunt amplifier allows for current sensing in order to measure motor current and provide feedback to the external controller for current limiting or stall detection.The DRV8705-Q1 provide an array of protection features to ensure robust system operation. These include under and overvoltage monitors for the power supply and charge pump, 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
