MC33932EKR2

Overview

The MC33932EKR2 is a dual half-bridge gate driver designed for throttle control applications. It features four drivers with a peak output current of 5 A per channel. The device operates within a supply voltage range of 5 V to 28 V and supports an operating temperature range from -40 °C to +125 °C. Key electrical parameters include a rise time and fall time of 3 µs, an open delay time of 1 ms, and an on-resistance (Rds On) of 120 mΩ. It is housed in an HSOP-54 package.

Feature Summary

• Dual half-bridge configuration supporting independent motor or solenoid control
• Integrated throttle control functionality for automotive applications
• High current capability with 5 A output drive per channel
• Robust thermal performance suitable for high-temperature environments

Applications

• Automotive throttle body control systems
• Brushed DC motor driving in powertrain applications

Procurement Notes

Verify component authenticity through authorized NXP distributors or certified partners. Confirm the specific suffix 'EK' matches the required HSOP-54 package variant. Check for end-of-life status as indicated by some sources, and validate RoHS compliance details against the latest official datasheet revision before finalizing procurement plans.

Selection Notes

Select this component when a dual H-bridge driver with integrated throttle control logic is required. Ensure the system voltage remains within the 5 V to 28 V range. Verify that the HSOP-54 package footprint fits the PCB layout constraints. Consider the 5 A peak current rating against the maximum load requirements of the connected motors or solenoids.

Part Context

The MC33932 belongs to NXP's portfolio of motor and motion controllers specifically tailored for automotive powertrain and engine control units. It complements other devices like the MC33931 and MC33813 series, focusing on high-current half-bridge applications. This part is distinct from general-purpose gate drivers due to its specialized integration for throttle and motor control functions.
