MC33883HEGR2

Overview

The MC33883HEGR2 is a four-channel half-bridge gate driver manufactured by NXP Semiconductors, designed for high-voltage power switching applications. It operates within a supply voltage range of 5.5 V to 55 V and delivers a peak output current of 1 A per channel. The device features independent non-inverting inputs and supports MOSFET gate driving with a maximum dead time of 200 ns. It is housed in a 20-SOIC surface-mount package and is qualified under the AEC-Q100 standard for automotive reliability. The component functions across an extended temperature range from -40°C to +125°C.

Feature Summary

• Four independent half-bridge channels for simultaneous control of multiple power switches
• Automotive-grade qualification ensuring robust performance in demanding environments
• Integrated dead-time control mechanism to prevent shoot-through conditions
• Non-inverting logic input configuration for straightforward interface compatibility

Applications

• Brushed DC motor control systems
• Solenoid actuation circuits
• High-side and low-side power switching applications

Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status. Confirm lot traceability and storage history to mitigate moisture sensitivity risks associated with the SOIC package. Ensure compliance with RoHS directives as specified in official documentation before integration into final assemblies.

Selection Notes

Select this component when four isolated half-bridge drivers are required within a single integrated circuit. Consider the 55 V maximum supply limit and 1 A drive capability against load requirements. Evaluate the 20-SOIC footprint constraints and thermal dissipation needs relative to the system's ambient operating conditions and duty cycle specifications.
