Microchip MTD6505T-E/NA

Привод - полностью интегрированный, ступень управления и питания1A2 В ~ 5,5 В

Overview

The MTD6505T-E/NA device is a 3-phase full-wave sensorless driver for brushless DC (BLDC) motors. It features 180° sinusoidal drive, high torque output and silent drive. With the adaptive features, parameters and wide range of power-supplies (2V to 5.5V), the MTD6505T-E/NA is intended to cover a broad range of motor characteristics, while requiring minimum external components. Speed control can be achieved through either power supply modulation (PSM) or pulse-widthmodulation (PWM).The compact packaging and the minimal bill-of-materialmake the MTD6505T-E/NA device extremely cost efficient in fan applications. For example, the CPU cooling fans in notebook computers require designs that provide low acoustic noise, low mechanical vibration, and are highly efficient. The frequency generator (FG) output enables precision speed control in closed-loop applications.The MTD6505T-E/NA device includes Lockup Protectionmode to turn off the output current when the motor is ina lock condition, with an automatic recovery feature torestart the fan when the lock condition is removed.Motor overcurrent limitation and thermal shutdown protection are included for safety enhanced operations.
