Texas Instruments DRV8363-Q1 48V Battery 3-Phase Smart Gate Driver
Texas Instruments DRV8363-Q1 48V Battery Three-Phase Smart Gate Driver provides three half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. The DRV8363-Q1 generates the correct gate drive voltages using an external 12V supply and an integrated bootstrap diode for the high-side MOSFETs. The Smart Gate Drive architecture supports configurable peak gate drive current from 16mA up to 1A source and 2A sink. The DRV8363-Q1 can operate with a wide input range from 8V to 85V at the motor connection. A trickle charge pump allows the gate drivers to support 100% PWM duty-cycle control and provides overdrive gate-drive voltage for external switches.
The Texas Instruments DRV8363-Q1 provides low-side current-sense amplifiers to support resistor-based low-side current sensing. The low offset of the amplifiers enables the system to obtain precise motor current measurements. A wide range of protection and diagnostics features, integrated with the DRV8363-Q1, enables a robust motor drive system design and helps eliminate the need for external components. The highly configurable device response enables seamless integration into a wide range of system designs.
