MP6532GR-P Monolithic Power Systems

MP6532 5V to 60V, Three-Phase Brushless DC Motor Pre-Driver DESCRIPTION FEATURES The MP6532 is a gate driver IC designed for Wide 5V to 60V Input Voltage Range three-phase brushless DC motor driver Built-in Hall Sensor Inputs and 120 applications. It is capable of driving three half Commutation Logic bridges consisting of six N-channel power Charge Pump Gate Drive Supply MOSFETs up to 60V. Bootstrap High-Side Driver with Trickle- Charge Circuit Supports 100% Duty Cycle The MP6532 integrates a regulated charge pump Operation to generate gate drive power, and uses a Low-Power Sleep Mode bootstrap capacitor to generate a supply voltage Programmable Short-Circuit Protection for the high-side MOSFET driver. An internal Over-Current Protection trickle-charge circuit maintains sufficient high- side gate driver voltage even when an output is Adjustable Dead-Time Control to Prevent operated at 100% duty cycle Shoot-Through Thermal Shutdown and UVLO Protection Internal protection features include Fault Indication Output programmable short-circuit protection, over- Thermally Enhanced Surface-Mount Package current protection, adjustable dead-time control, undervoltage lockout, and thermal shutdown. APPLICATIONS The device integrates 120 commutation using Three-Phase Brushless DC Motors and three Hall sensor inputs. The PWM, DIR, and Permanent Magnet Synchronous Motors nBRAKE inputs are used to control motor speed, Power Drills direction, and braking. Impact Drivers The MP6532 is available in 28-pin, 9.7mm E-Bike 6.4mm TSSOP and 4mm x 4mm QFN packages All MPS parts are lead-free, halogen-free and adhere to the RoHS directive. with an exposed thermal pad.
