MPQ6610GJ-AEC1-P

Overview

The MPQ6610GJ-AEC1-P is an automotive-grade half-bridge power driver manufactured by Monolithic Power Systems. It operates within a supply voltage range of 4 V to 55 V and delivers up to 3 A output current. The device features low on-resistance with 100 mΩ for the high-side FET and 120 mΩ for the low-side FET. It includes integrated current sensing, cycle-by-cycle current regulation, and protection mechanisms such as overcurrent protection (OCP), under-voltage lockout (UVLO), over-temperature shutdown, and load open detection. The component is housed in a TSOT23-8 package and supports logic inputs compatible with 2.5 V, 3.3 V, and 5 V systems.

Feature Summary

• Integrated current measurement circuit providing a voltage output proportional to load current without requiring external low-impedance shunt resistors.
• Comprehensive diagnostic and protection suite including load open detection, overcurrent protection, under-voltage lockout, and over-temperature shutdown.
• Direct interface compatibility with standard 2.5 V, 3.3 V, and 5 V logic levels, eliminating the need for additional control power supplies.

Applications

• Brushed DC motor driving
• Solenoid actuation
• Automotive ignition systems

Procurement Notes

Verify that the specific part number suffix corresponds to the required packaging configuration, as MPS utilizes distinct suffixes for different tape-and-reel or cut-tape options. Confirm compliance with AEC-Q100 qualification standards for automotive deployment. Ensure design constraints account for the thermal limitations inherent to the TSOT23-8 package, particularly regarding maximum power dissipation ratings under continuous operation conditions.

Selection Notes

Select this component when a compact solution is required for driving inductive loads within a 55 V system. The TSOT23-8 package is suitable for applications where board space is limited, though designers must consider derating guidelines for voltages exceeding 45 V due to pin spacing constraints. This driver is appropriate for designs necessitating built-in current sensing capabilities to simplify bill-of-materials and reduce external component count.

Part Context

This device belongs to the MPQ6610 series of half-bridge drivers designed for automotive environments. It shares functional similarities with other MPS motor drivers but is distinguished by its specific package type and integrated sensing features. The series supports various packaging options, including SOIC-8 for enhanced thermal performance, allowing engineers to choose based on thermal management requirements and spatial constraints.

FAQ

What is the recommended maximum operating voltage for the TSOT23-8 package?

While the device supports input voltages up to 55 V, the TSOT23-8 package is only recommended for applications up to 45 V unless conformal coating or encapsulation is used.

Does the MPQ6610GJ-AEC1-P require an external bootstrap capacitor?

The datasheet specifies it as an internal half-bridge driver; however, specific external component requirements for gate drive bootstrapping should be verified against the official electrical characteristics table.
