MP6551GQB-P

Overview

The MP6551GQB-P is a dual H-bridge motor driver manufactured by Monolithic Power Systems. It operates within a supply voltage range of 2.5V to 14V and supports continuous output currents up to 5A per channel. The device is housed in a QFN-14 surface-mount package, suitable for compact designs. It functions across an extended temperature range from -40°C to +125°C. Key electrical characteristics include a maximum power dissipation of 1.92W and two independent output channels. This component is classified under electromechanical drivers and PMICs.

Feature Summary

• Dual H-bridge architecture enabling bidirectional control of two DC motors or one stepper motor
• Integrated high-side and low-side MOSFETs for efficient power switching
• Logic-compatible input interface for direct connection to microcontrollers
• Thermal shutdown protection to safeguard the device during overload conditions

Applications

• Small appliance motor control systems
• Robotics actuator drive circuits
• Automotive window and seat adjustment mechanisms
• Industrial automation valve controllers

Procurement Notes

Verify the specific suffix 'P' against official MPS documentation to confirm packaging configuration and material compliance. Ensure the ordering part number matches the required tape-and-reel specifications. Cross-reference the manufacturer's latest datasheet for any revisions to pinout or thermal parameters before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring dual-channel DC motor control with moderate current demands. The 14V rating suits low-voltage automotive and consumer applications. Consider the QFN-14 package for space-constrained PCB layouts. Evaluate thermal management requirements given the 1.92W power dissipation limit at full load.
