Overview
The MPC17531ATEVEL is a monolithic dual H-bridge power IC designed for portable electronic applications. It integrates internal control logic, a charge pump, gate drivers, and high-current low RDS(on) MOSFET output circuitry. The device supports bipolar stepper motors and brushed DC motors with a supply voltage range of 2.7V to 3.6V and load voltage up to 8.6V. It features a 700mA output current capability and operates within a junction temperature range of -20°C to 150°C. Packaged in a 20-VMFP surface-mount case, it offers a fully integrated solution for motor control.
Feature Summary
- Integrates internal control logic, charge pump, and gate drive for simplified system design
- Features high-current, low RDS(on) MOSFET output circuitry for efficient power handling
- Supports driving single two-phase stepper motors or two brushed DC motors
- Provides full integration of control and power stages in a compact package
Applications
- Portable electronic devices requiring bipolar step motor control
- Systems utilizing brush DC motors
- Battery-powered equipment
- Embedded motion control modules
Procurement Notes
Verify component status as the MPC17531ATEVEL is listed as obsolete by NXP USA Inc. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure compatibility with existing board designs before procurement due to end-of-life status. Check for alternative replacement parts from the manufacturer if long-term supply stability is a priority.
Selection Notes
Select this component for applications requiring a compact, fully integrated dual H-bridge driver for low-voltage motors. It is suitable for systems needing 700mA per channel with bipolar stepper or brushed DC motor support. Consider the 20-VMFP package constraints and thermal management requirements for the specified operating temperature range. Verify that the 2.7V to 3.6V supply range aligns with the system power architecture.
Part Context
The MPC17531A series includes variants such as MPC17531ATEP and MPC17531ATEPR2. These components share similar functional characteristics but differ in packaging and tape/reel options. The ATEVEL variant specifically utilizes a 20-VMFP package. Evaluation boards like FRDM-17531EV-EVB demonstrate its application capabilities for motor driving tasks.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the part is obsolete, consult NXP Semiconductors for recommended replacements or equivalent dual H-bridge drivers with compatible voltage and current specifications.
