MP9517GJL-Z

Overview

The MP9517GJL-Z is a single-phase brushless DC motor driver manufactured by Monolithic Power Systems. It integrates Hall sensor signal processing, gate drivers, and power MOSFETs into a TSOT23-6-L package. The device supports a supply voltage range of 3.3 V to 18 V with a maximum output current of 2 A. Operating frequencies span from 2 kHz to 100 kHz, while the quiescent current is 6.5 mA. It functions within a temperature range of -40°C to +125°C and dissipates up to 1.25 W.

Feature Summary

• Integrates Hall sensor interface for commutation control
• Combines PWM controller with half-bridge power stage
• Supports variable frequency operation for speed regulation

Applications

• Single-phase BLDC fan cooling systems
• Small appliance motor control
• Industrial actuator drives

Procurement Notes

Verify the specific suffix 'Z' indicates lead-free compliance against the manufacturer's latest documentation. Confirm the TSOT23-6-L footprint matches the target PCB layout. Ensure the operating voltage requirements align with the 3.3 V to 18 V specification before finalizing procurement.

Selection Notes

Select this component for applications requiring a compact solution for single-phase BLDC motors. The integrated Hall sensor interface reduces external component count. Verify that the 2 A output current capability meets the load requirements and that the thermal performance in the TSOT23-6-L package is sufficient for the expected power dissipation.

Part Context

This part belongs to the MP9517 series of motor controllers designed for low-power BLDC applications. It serves as an alternative to discrete driver solutions by integrating control logic and power stages. The device is categorized under PMIC and Motor Drivers within the manufacturer's portfolio.
