Texas Instruments DRV8106-Q1 Automotive Smart Gate Drivers

Texas Instruments DRV8106-Q1 Automotive Half-Bridge Smart Gate Drivers are capable of driving high-side and low-side N-channel power MOSFETs. The DRV8106-Q1 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 TI DRV8106-Q1 Automotive Half-Bridge Smart Gate Drivers use 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 decrease electromagnetic interference (EMI) through the adjustable gate drive current, and protects against drain to source and gate short conditions with V_DS and V_GS monitors.

The DRV8106-Q1 Gate Drivers offer an array of protection features to ensure robust system operation. These features include under and overvoltage monitors for the power supply and charge pump, V_DS overcurrent, and V_GS gate fault monitors for the external MOSFETs, offline open load and short circuit diagnostics, and internal thermal warning and shutdown protection.
