Overview
The MC34937APEK is a three-phase field-effect transistor (FET) pre-driver utilizing SMARTMOS technology, designed for motor control applications. It integrates three high-side and three low-side FET pre-drivers with a gate drive capability exceeding 1.0 A. The device operates within an extended supply voltage range of 6.0 V to 58 V, supporting 12 V and 42 V automotive systems. It features a programmable deadtime via SPI, protection against reverse charge injection, and accepts both 5.0 V and 3.0 V logic level inputs.
Feature Summary
- Integrates three high-side and three low-side FET pre-drivers using SMARTMOS technology
- Provides greater than 1.0 A gate drive capability with integrated charge pump support
- Includes protection mechanisms against reverse charge injection from external FETs
- Offers programmable deadtime configuration through the serial peripheral interface
Applications
- Three-phase motor control systems
- Automotive powertrain applications

Procurement Notes
Verify the specific suffix 'PEK' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the ordering part number matches the exact temperature grade and qualification status required for the target application environment. Cross-reference the component marking code with the latest errata documentation to identify any mask revisions or known operational limitations associated with this specific manufacturing lot.
Selection Notes
Select this component when designing systems requiring integrated pre-driving for three-phase FET topologies with high current drive requirements. The device is suitable for environments demanding extended operating voltage ranges up to 58 V. Consider the SPI interface for dynamic deadtime adjustment and system monitoring. Evaluate the thermal performance of the SOIC package relative to the expected load current and ambient conditions during the design phase.
Part Context
This component belongs to NXP's portfolio of gate drivers and power management ICs specifically engineered for robust motor control. It complements other NXP solutions by providing the necessary interface between microcontrollers and external power switches. The integration of SMARTMOS technology allows for compact designs while maintaining high reliability in automotive and industrial sectors.
Replacement Considerations
Consult the official NXP product longevity program documentation for confirmed substitute part numbers. Verify pin compatibility and electrical parameter equivalence before substitution. No direct public substitutes are listed in the provided reference data.
