MPQ6532GVE-AEC1-Z

MPQ6532 5V to 60V, Three-Phase Brushless DC Motor Pre-Driver, AEC-Q100 Qualified DESCRIPTION FEATURES The MPQ6532 is a gate driver IC designed for three-phase brushless DC (BLDC) motor driver applications. It is capable of driving three halfbridges, consisting of six N-channel power MOSFETs, up to 60V. • • The MPQ6532 integrates a regulated charge pump to generate gate drive power, and uses a bootstrap (BST) capacitor to generate a supply voltage for the high-side MOSFET (HS-FET) driver. An internal trickle-charge circuit maintains a sufficient HS-FET driver voltage even when the output is at 100% duty cycle. Internal safety features include configurable short-circuit protection (SCP), over-current protection (OCP), adjustable dead-time (DT) control, under-voltage lockout (UVLO), and thermal shutdown. • • • • • • • • • • The MPQ6532 integrates 120° commutation using three Hall sensor inputs. The pulse-width modulation (PWM), DIR, and nBRAKE inputs control the motor speed, direction, and braking, respectively. • • The MPQ6532 is available in a QFN-28 (4mmx5mm) package with an exposed thermal pad, and is AEC-Q100 qualified. • • Wide 5V to 60V Input Voltage (VIN) Range Built-in Hall Sensor Inputs and 120° Commutation Logic Charge Pump Gate Drive Supply Bootstrap (BST) High-Side (HS) Driver with Trickle-Charge Circuit Supports 100% Duty Cycle Operation Low-Power Sleep Mode Configurable Short-Circuit Protection (SCP) Over-Current Protection (OCP) Adjustable Dead-Time (DT) Control to Prevent Shoot-Through Pulse-Width Modulation (PWM) Speed Control Input Brake Control Input Motor Start-Up Current Limit Thermal Shutdown and Under-Voltage Lockout (UVLO) Protection Fault Indication Output Thermally Enhanced Surface-Mount Package Available in a QFN-28 (4mmx5mm) Package Available in AEC-Q100 Grade 1 APPLICATIONS • • Three-Phase Brushless DC (BLDC) Motors and Permanent Magnet Synchronous Motors (PMSMs) Automotive Actuators, Pumps, and Fans All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
