MP6543 12V, 2A, Three-Phase Power Stage DESCRIPTION FEATURES The MP6543 family of products are all three- 3V to 12V Operating Supply Voltage phase brushless DC motor drivers. They Three Integrated Half-Bridge Drivers integrate three half-bridges, consisting of six N- 2A Continuous Output Current channel power MOSFETs, along with pre- MOSFET On Resistance: 110m per FET drivers, gate drive power supplies, and current- MP6543: ENBL & PWM Inputs sense amplifiers. MP6543A: LS & HS Inputs MP6543B: Hall-Signal Inputs The MP6543 has ENABLE and PWM inputs for Built-In 3.3V, 100mA LDO Regulator each -H-bridge. The MP6543A has separate Internal Charge Pump Supports 100% Duty high-side and low-side inputs, while the MP6543B has Hall-element inputs. Otherwise, Cycle Operation they are similar. References to the MP6543 in Automatic Synchronous Rectification this document apply to the other parts, unless Under-Voltage Lockout (UVLO) and otherwise noted. Thermal Shutdown Protection Over-Current Protection (OCP) with The MP6543 is able to deliver up 2A Adjustable Threshold continuously (depending on thermal and PCB Integrated Bidirectional Current-Sense conditions), with the adjustable over-current Amplifiers protection threshold. It uses an internal charge Available in a QFN-24 (3mmx4mm) pump to generate the gate drive supply voltage Package for the high-side MOSFETs, and a trickle- charge circuit to maintain sufficient gate drive APPLICATIONS voltage to operate at 100% duty cycle. Three-Phase BLDC Motor Drivers Internal safety features include thermal All MPS parts are lead-free, halogen free, and adhere to the RoHS shutdown, under-voltage lockout (UVLO), and directive. For MPS green status, visit the MPS website under Quality over-current protection (OCP). Assurance.
