MP6616B

18V, 2A, Single-Phase BLDC Motor Driver with Closed-/Open-Loop Speed Control and Enhanced ESD Capability

データシート

概要

The MP6616B is a single-phase, brushless DC (BLDC) motor driver with integrated MOSFETs and an embedded Hall-effect sensor. It can drive up to 2A of continuous output current (I_OUT) across a 3.3V to 18V input supply voltage (V_CC) range.

The MP6616B supports both speed open-loop and closed-loop control. The speed is controlled via the pulse-width modulation (PWM) signal on the PWM pin. The device features a configurable soft commutation angle and Hall offset angle. The Hall offset angle can be flexibly optimized for low-speed and high-speed performance across the full speed range.

The FG/RD pin can function as a rotational speed detector or rotor deadlock indicator. This pin is an open-drain output that must be pulled up externally.

Rich protection features include input over-voltage protection (OVP), under-voltage lockout (UVLO) protection, locked-rotor protection, over-current protection (OCP), and thermal shutdown.

The MP6616B is available in a QFN-10 (2mmx3mm) package.
