MC33GD3000EP

Overview

The MC33GD3000EP is a three-phase brushless motor pre-driver IC designed for automotive and industrial applications. It integrates three half-bridge drivers, each capable of driving two N-channel MOSFETs with peak currents ranging from 1 A to 2.5 A. The device operates on a single power supply within an extended voltage range of 6 V to 60 V, featuring 75 V transient protection. Key technical specifications include a programmable dead time between 50 ns and 12 μs via SPI, integrated VDS sensing for overcurrent protection, and a current shunt amplifier for phase error detection. It supports 3.3 V and 5.0 V logic interfaces and includes a charge pump for low-voltage FET drive.

Feature Summary

• Integrates three half-bridge drivers with bootstrap architecture supporting 100% duty cycle
• Features programmable cross-talk protection and integrated VDS sensing for external FET safety
• Includes a current shunt amplifier for precise phase current measurement and error detection
• Supports direct MCU connection with 3.3 V and 5.0 V logic level compatibility

Applications

• Brake and stability control systems
• Diesel engine management
• Electric power steering (EPS) systems

Procurement Notes

Verify the specific suffix 'EP' against official NXP documentation to confirm package type and temperature grade. Ensure the ordering part number matches the exact revision required for your design. Confirm compliance with AEC-Q100 standards if used in automotive contexts. Check for any recent product change notifications that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when designing three-phase BLDC or PMSM motor drives requiring high-side and low-side gate driving capabilities. It is suitable for applications needing integrated fault detection such as desaturation and phase failure. Consider its wide operating voltage range and SPI configurability for flexible system integration. Ensure the external MOSFETs are compatible with the driver's peak current output and voltage ratings.
