With a comprehensive diagnosis and protection function
Worcester, Massachusetts,- Allegro to launch a new three-phase sensorless brushless dc (BLDC) motors, motor controller, used for external N channel power MOSFET, its design can be applied to a variety of automotive applications such as pump, fan and cooling fan.Motor commutation (trapezoid commutation) driven by blocking, the commutation without the need for a separate position sensor, through the motor back emf monitoring decision.Programmable design can make the motor start AllegroA4960Adjustment for a large number of motor and load combination.
External bootstrap capacitor is used to provide the necessary drive N channel MOSFET the battery power supply voltage.Automatic bootstrap internal load management design can ensure the bootstrap capacitor is always provide sufficient power to the safe operation of power MOSFET.Integrated control and adjustable dead time can make the power MOSFET from breakdown.
Integrated diagnosis may indicate undervoltage, moderate power bridge fault, and can be configured in the most short circuit conditions to protect power FET.Detailed diagnostic by serial data word or programmable output form.A4960采用 32 引线 eLQFP 封装（后缀 JP）。所有封装均为无铅版本，引脚框采用100% 雾锡电镀（–T）。
