MP6500 35V, 2.5A, Stepper Motor Driver DESCRIPTION FEATURES The MP6500 is a stepper motor driver with a Wide 4.5V to 35V Input Voltage Range built-in translator and current regulation. Two Internal Full-Bridge Drivers Current sensing is internal and requires no Internal Current Sensing and Regulation external sense resistors. High integration and a Low On Resistance (HS: 195m, LS: small package size make the MP6500 a space- 170m) saving and cost-effective solution for bipolar No Control Power Supply Required stepper motor drives. Simple Logic Interface 3.3V and 5V Compatible Logic Supply The MP6500 operates from a supply voltage of up to 35V and can deliver motor currents up to Step Modes from Full-Step to Eighth-Step 2.5A (depending on PCB design and thermal 2.5A Output Current conditions). The MP6500 can operate a bipolar Automatic Current Decay stepper motor in full-, half-, quarter-, or eighth- Over-Current Protection (OCP) step modes. 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 Available in QFN-24 (5mmx5mm) and The MP6500 is available in QFN-24 Thermally Enhanced TSSOP-28 Packages (5mmx5mm) and TSSOP-28 EP packages.
