MP6508GR-P Monolithic Power Systems

WindingB MP6508 2.7V-to-18V, 1.2A, Bipolar Stepper Motor Driver with Integrated MOSFETs DESCRIPTION FEATURES The MP6508 is a bipolar stepper-motor driver Wide 2.7V to 18V Input Voltage Range with dual, built-in full-bridges consisting of N- Two Internal Full Bridge Drivers channel power MOSFETs. Low On Resistance(HS:250m LS:250m) Internal Charger Pump for the High-Side It operates from a supply voltage ranging from Driver 2.7V to 18V and can deliver motor current up Low Quiescent Current:1.6mA to 1.2A per channel. The Internal safety Low Sleep Current: 1uA features include over-current protection(OCP), Over-Current Protection under-voltage lockout protection(UVLO) and thermal shutdown. A fault output flag is Thermal Shutdown and UVLO Protection available to indicate OCP and thermal Fault Indication Output shutdown. Thermally-Enhanced Surface-Mount Package The MP6508 comes in both 16-pin, 5.0mmx6.4mm TSSOP-EP and 4mmx4mm APPLICATIONS QFN package with an exposed thermal pad on POS Printers the backside.
