The MPQ6614-AEC1 and MP6614 are 5V to 35V input voltage (VIN) range, 1.5A (MPQ6614-AEC1) or 2A (MP6614) continuous output current (IOUT), H-bridge DC motor drivers. The MPQ6614-AEC1’s high-side and low-side MOSFET on resistance (RDS(ON)) can reach as low as 440mΩ. The MP6614’s high-side and low-side MOSFET RDS(ON) can reach as low as 500mΩ.
The internal charge pump supports 100% duty cycle operation. In addition, the MPQ6614-AEC1 and MP6614 integrate an internal current-sense circuit that provides an output with a voltage that is proportional to the load current. Cycle-by-cycle current regulation and limiting are also provided.
Moreover, the MPQ6614-AEC1 and MP6614 support 3.3V and 5V compatible logic supply. Internal protection features include under-voltage lockout (UVLO), over-current protection (OCP), short-circuit protection (SCP), and thermal shutdown. The MPQ6614-AEC1 is available in a small QFN-8 (2mmx3mm) package, and the MP6614 is available in an SOIC-8EP package.
They are designed for solenoid drivers and brushed DC motor drivers such as automotive HUD control, automotive water pumps and valves, massage chairs, sweeper robots, and coffee machines.
Monolithic Power Systems provides small, highly energy efficient, easy-to-use power solutions for systems found in industrial applications, telecom infrastructures, cloud computing, automotive, and consumer applications.
