Product Summary

The NCD83591 is an easy-to-use 60 V multi-Our Group's Purpose three-phase gate driver with a high gain bandwidth current sense amplifier, ideal for trapezoidal wave control motor applications. The gate drive current of the output stage power MOSFET can be adjusted by an external voltage divider resistor value, and the charge current can be set in the range of 5 to 250 mA (discharge current is twice the charge current).

In addition, the NCD83591 built-in voltage regulator generates the internal gate driver circuit drive voltage from the motor voltage of 5 to 60 V, so it can operate with a single power supply. The QFN 28 (4mm x 4mm) package allows the design of three-phase motor drive circuits in a small footprint.

Main features/functions

• Operating voltage from 5 V to 60 V (maximum rating of 70 V)
• Constant current drive for power MOSFET, configurable from 5 mA to 250 mA (16 settings depending on input level to VDRV pin)
• Internally generated gate drive supply voltage
• Gate sensing for cross-conduction protection and optimized dead time
• Built-in high GBW general-purpose amplifier (for current sensing, externally configurable)
• Built-in charge pump function capable of DC static drive
• Six control and enable inputs for 5 V/3.3 V
• Up to 30 kHz motor PWM (individual 6 gate control mode)

Application diagram

Gate sensing and dead time

The IL input is active low and the IH input is active high.
Even if the same pulse signal is input to IL and IH, the gate sensing of NCD83591 causes the port that has already output High to fall, and after the dead time (txcp) elapses, the next output port becomes High.

Application example

・Power tools
・Factory automation/collaborative robots/transport robots
・Electric bicycle/Electric scooter
