概述

Description

MP3398AGS-Z is a high-performance motor-driver IC from Monolithic Power Systems (MPS) designed to drive brushless DC motors and stepper motors with integrated power MOSFETs. It provides efficient, compact motor control with minimal external components.
Key points
- Integrated power bridge: N-channel MOSFETs for smooth, high-current motor drive
- Adjustable current limit via sense resistor
- Protection: undervoltage lockout, overcurrent, overtemperature/overvoltage
- Supports motor-drive features such as microstepping/decay options for smooth motion
- Suitable for compact, low-footprint applications
Packaging
- AGS-Z denotes a RoHS-compliant, compact QFN-style package variant with specific lead/frame options (check datasheet for exact pinout and packaging details)
Typical applications
- Robotics, printers, CNC/automation, and other precision motor-control tasks
Note
- For exact electrical specs (voltage range, peak/current ratings) and pinout, refer to the MP3398AGS-Z datasheet and product brief.

Features

Key features of MP3398AGS-Z (summary):
- 3-phase brushless DC motor driver with integrated MOSFETs
- Wide supply range (approximately 4.5–28 V)
- Programmable peak current with accurate current regulation
- PWM control with selectable decay modes; supports smooth sine/six-step commutation
- Sensorless commutation using back-EMF detection for startup and run
- Built-in protection: overcurrent, overvoltage, undervoltage, overtemperature; short-circuit protection
- Fault diagnostics and status outputs for monitoring
- Enable (EN) and DIR/PWM-style control interface for direction and speed
- Compact AGS-Z package (QFN-style) with good thermal performance
Note: For exact electrical specs, pinout, and programming registers, refer to the MP3398AGS-Z datasheet.
