MP6500L 35V, 2.5A Stepper Motor Driver with Internal Current Sense DESCRIPTION FEATURES The MP6500L is a stepper motor driver with Wide 4.5V to 35V Input Voltage Range current regulation and a built-in translator. Two Internal Full-Bridge Drivers Current sensing is internal and does not require Internal Current Sensing and Regulation external sense resistors. With high integration Low On Resistance (195m HS-FET, and a small package size, the MP6500L is a 170m LS-FET) space-saving, cost-effective solution for bipolar No Control Power Supply Required stepper motor drives. Simple Logic Interface 3.3V and 5V Compatible Logic Supply The MP6500L operates from a supply voltage up to 35V and can deliver motor currents up to Step Modes from Full Step to Eighth-Step 2.5A based on PCB design and thermal 2.5A Output Current conditions. The MP6500L can operate a bipolar Automatic Current Decay stepper motor in full-, half-, quarter-, or eighth- Over-Current Protection (OCP) step mode. Internal safety features include Input Over-Voltage Protection (OVP) over-current protection (OCP), input over- Thermal Shutdown and Under-Voltage voltage protection (OVP), under-voltage lockout Lockout (UVLO) Protection (UVLO), and thermal shutdown. Fault Indication Output The MP6500L is available in a QFN-24 Available in a QFN-24 (5mmx5mm) Package (5mmx5mm) package.
