MP6614 Datasheet | Monolithic Power Systems

DESCRIPTION The MP6614 is an H-bridge motor driver designed to drive reversible motors. The device can drive one DC motor, one winding of a stepper motor, or other loads. The H-bridge integrates four N-channel power MOSFETs, and an internal charge pump generates the required gate driver voltages. The MP6614 operates across a 5V to 35V input supply (VIN) range. It can deliver up to 2A of continuous current (IOUT), depending on the thermal and PCB layout. The MP6614 provides a pulse-width modulation (PWM) input interface that is patible with industry-standard devices. A brake is applied to stop the motor, and a very low standby circuit current can be achieved when the device is disabled. An internal current-sense circuit provides an output voltage (VISEN) that is proportional to the load current (IOUT). In addition, cycle-by-cycle current regulation and limiting are provided. These features do not require a low-ohmic shunt resistor. Internal protection features include over-current protection (OCP), short-circuit protection (SCP), under-voltage lockout (UVLO), and overtemperature protection (OTP). The MP6614 requires a minimal number of readily available, standard external ponents. The MP6614 is available in a SOIC-8EP package. 35V, H-Bridge DC Motor Driver with SOIC-8 Package FEATURES - Wide 5V to 35V Operating Input Voltage (VIN) Range - Internal Full H-Bridge Driver Supports 100% Duty Cycle - 2A Continuous Output Current (IOUT) - Low On Resistance (RDS(ON)) per MOSFET: o 280mΩ High-Side MOSFET (HS-FET) o 220mΩ Low-Side MOSFET (LS-FET) - Simple, Versatile Logic Interfaces - 3.3V and 5V patible Logic Supply - Cycle-by-Cycle Current Regulation and Limiting - Low Standby Circuit Current - Over-Current Protection (OCP) - Thermal Shutdown - Under-Voltage Lockout (UVLO) - Internal Charge Pump - Available in a Thermally Enhanced, Surface-Mounted SOIC-8EP Package APPLICATIONS - Solenoid Drivers - Brushed DC Motor Drivers All MPS parts are lead-free, halogen-free,...
