Brushless DC Motor Gate Driver, 3-Phase, 5-60V, 1A, QFN 56

The GD3000 is a gate driver IC for three-phase motor drive applications providing three half-bridge drivers, each capable of driving two N-channel MOSFETs.

* Supports 1 A to 2.5 A peak current capability

* Can operate off of a single power supply with a wide range from 6 V to 60 V with 75 V transient protection

* Uses a bootstrap gate driver architecture with trickle charge circuitry to support 100% duty cycle

* Uses programmable cross-talk protection when the high-side or low-side MOSFET is switching to prevent flow of current

* Integrated VDS sensing of the high-side and low-side MOSFETs is used to protect the external power stage against over-current conditions

* Includes a current shunt amplifier for accurate current measurement for phase error detection

The IC interfaces to a MCU via six direct input control signals, a SPI port for device setup and asynchronous reset, enable and interrupt signals. Both 5.0 and 3.0 V logic level inputs are accepted and 5.0 V logic level outputs are provided.
