MP6600L Datasheet | Monolithic Power Systems

DESCRIPTION The MP6600L is a stepper motor driver with current regulation and a built-in translator. Current sensing is internal and does not require external sense resistors. With high integration and a small package size, the MP6600L is a space-saving, cost-effective solution for bipolar stepper motor drives. The device operates with a supply voltage up to 35V and can deliver motor currents up to 1.5A based on PCB design and thermal conditions. The MP6600L can operate a bipolar stepper motor in full-, half-, quarter-, or eighth-step mode. Internal safety features include overcurrent protection (OCP), input over-voltage protection (OVP), under-voltage lockout (UVLO), and thermal shutdown. The MP6600L is available in a QFN-24 (4mmx4mm) package. 35V, 1.5A Stepper Motor Driver with Internal Current Sense FEATURES - Wide 4.5V to 35V Input Voltage Range - Two Internal Full-Bridge Drivers - Internal Current Sensing and Regulation - Low On Resistance (195mΩ HS-FET, 170mΩ LS-FET) - No Control Power Supply Required - Simple Logic Interface - 3.3V and 5V patible Logic Supply - Step Modes from Full Step to Eighth-Step - 1.5A Output Current - Automatic Current Decay - Over-Current Protection (OCP) - Input Over-Voltage Protection (OVP) - Thermal Shutdown and Under-Voltage Lockout (UVLO) Protection - Fault Indication Output - Available in a QFN-24 (4mmx4mm) Package APPLICATIONS - Bipolar Stepper Motors - Printers All MPS parts are lead-free, halogen-free, and adhere to the Ro HS directive.
