MPQ6532-AEC1

5V to 60V, Three-Phase Brushless DC Motor Pre-Driver, AEC-Q100 Qualified

Description

The MPQ6532 is a gate driver IC designed for three-phase brushless DC (BLDC) motor driver applications. It is capable of driving three half-bridges, consisting of six N-channel power MOSFETs, for an input voltage (V_IN) up to 60V.

The device includes a regulated charge pump that generates gate driver power, and it 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 while the output is operating at 100% duty cycle.

The MPQ6532 integrates 120° commutation using three Hall sensor inputs. The PWM, DIR, and nBRAKE pins control the motor speed, direction, and braking.

Internal safety features include configurable short-circuit protection (SCP), over-current protection (OCP), adjustable dead time (DT) control, under-voltage lockout (UVLO) protection, and thermal shutdown. The MPQ6532 is available in a QFN-28 (4mmx5mm) package with an exposed thermal pad, and is AEC-Q100 qualified.
