MP6603 Datasheet | Monolithic Power Systems

DESCRIPTION The MP6603 is a dual full-bridge motor driver with integrated low-on resistance (RDS(ON)) MOSFETs. High integration and a small QFN package make the MP6603 a cost-effective solution for brushed DC motor drivers and stepper motor drivers. The MP6603 operates across an 8V to 55V input voltage (VIN) range. It can deliver a motor current up to 5A peak per full bridge, depending on the ambient temperature and PCB layout. The MP6603 has unique independent ground pins for each half-bridge. These pins make it possible to provide current measurements through the external shunt resistor. Two configurable input modes are available for the MP6603: a pulse-width modulation (PWM) input interface and an indexer interface. The IN_SEL pin configures the input interface. Internal safety and diagnostic features include over-current protection (OCP), short-circuit protection (SCP), under-voltage protection (UVP), and thermal shutdown. The MP6603 is available in a QFN-25 (4mmx5mm) package. 55V, Dual Full-Bridge Motor Driver with Internal Current Sense FEATURES - Wide 8V to 55V Operating Input Voltage (VIN) Range - Two Internal Full-Bridge Drivers - Selectable Input Interface: Simple Pulse- Width Modulation (PWM) Input or Indexer Input) - Indexer Interface Offers Full-, Half-, Quarter-, and Eighth-Step Modes by Setting the M1 and M2 Pins - Low On Resistance (RDS(ON)): 65mΩ High Side MOSFET (HS-FET) and 50mΩ Low Side MOSFET (LS-FET) - Up to 5A of Current in Full-Bridge Mode - Up to 10A of Current in Parallel Mode - PWM Operating Frequency Up to 100k Hz - Independent Ground Pins for Each Half Bridge - Over-Current Protection (OCP) - Thermal Shutdown - Under-Voltage Lockout (UVLO) - Internal Charge Pump - Fault Indication Output - Available in a Space-Saving QFN-25 (4mmx5mm) Package APPLICATIONS - Bipolar Stepper Motors - Brushed DC Motor Drivers All MPS parts are lead-free, halogen-free, and adhere to the Ro HS directive.
