MP6540H, MP6540HA 50V, 5A, Three-Phase Power Stage DESCRIPTION FEATURES The MP6540H and MP6540HA are three-phase 5.5V to 50V Operating Supply Voltage brushless DC motor drivers. These devices Three Integrated Half-Bridge Drivers integrate three half-bridges consisting of six N- Maximum 5A Output Current, 6A Peak channel power MOSFETs, pre-drivers, gate drive Current power supplies, and current-sense amplifiers. MOSFET On Resistance: HS + LS 45m MP6540H: PWM and Enable Inputs The MP6540H has enable (EN) and PWM inputs MP6540HA: HS and LS Inputs for each half-bridge, while the MP6540HA has Internal Charge Pump Supports 100% Duty separate high-side and low-side inputs. Cycle Operation Otherwise, both parts are identical. References Automatic Synchronous Rectification to the MP6540H in this document also apply to the MP6540HA, unless otherwise noted. UVLO and Thermal Shutdown Protection Over-Current Protection (OCP) The MP6540H can deliver up to 6A of peak Integrated Bidirectional Current-Sense current and 5A of continuous output current, Amplifiers based on thermal and PCB conditions. The Available in a QFN-26 (5mmx5mm) Package MP6540H uses an internal charge pump to generate the gate drive supply voltage for the APPLICATIONS high-side MOSFETs, and a trickle charge circuit Brushless DC Motors that maintains sufficient gate drive voltage to Permanent Synchronous Magnet Motors operate at 100% duty cycle. All MPS parts are lead-free, halogen-free, and adhere to the RoHS Internal safety features include thermal shutdown, directive. For MPS green status, please visit the MPS website under under-voltage lockout (UVLO), and over-current Quality Assurance.
