EVQ6634-LTE-00A

The EVQ6634-LTE-00A is an evaluation board designed to demonstrate the capabilities of the MPQ6634-AEC1, a 3-phase, sensorless brushless DC (BLDC) motor driver with integrated power MOSFETs. The MPQ6634-AEC1 provides sensorless field-oriented control (FOC) to achieve improved efficiency and low vibration with up to 2A of peak current. The input voltage (V_IN) range is between 4.5V and 35V.

The MPQ6634-AEC1 controls the motor speed through the pulse-width modulation (PWM) signal with a 50Hz to 20kHz PWM input frequency. The device supports DC input speed control. It also provides closed-/open-loop speed control and a built-in configurable speed curve function.

The MPQ6634-AEC1 provides rotational speed detection. The rotational speed detector (the FG/RD pin) is an open-drain output. In addition to rotation speed detection, the direction is controlled via the DIR pin input.

Rich protections include input over-voltage protection (OVP), under-voltage lockout (UVLO), locked-rotor protection, phase-loss protection (PLOS), over-current protection (OCP), and thermal shutdown protection (TSD).

The MPQ6634-AEC1 is available in a TQFN-12 (3mmx4mm) package with wettable flanks, and it is available in AEC-Q100 Grade 1.
