The original A4960KJPTR-T design was enhanced to improve EMC performance. Brushless Motor Driver Schematic The A4960 drives a motor using block commutation (trapezoidal drive) where phase commutation is determined, without the need for independent position sensors, by monitoring the motor back-EMF.

A programmable motor start-up scheme allows the A4960 to be adjusted for a wide range of motor and load combinations. Bldc Motor Controller Ic D) In English 中文内容 日本語表示 Description & parametrics Online datasheet Technical documents Tools & software Order Now Compare Quality & packaging Support & training Description Features Parametrics Diagrams Related end Each 1/2-H-bridge driver has a dedicated ground terminal, which allows independent external current sensing. http://www.ti.com/product/DRV8313 Allegro supports designs that are in progress or designs for those who cannot switch to the “-A” version.

An external bootstrap capacitor is used to provide the above battery supply voltage required for N-channel MOSFETs. 3 Phase Bldc Motor Driver Circuit This package is lead (Pb) free, with 100% matte-tin leadframe plating (suffix –T). While Allegro continues to support existing designs using the A4960KJPTR-T, it will transition all new designs and customers to the “-A” version. Integrated diagnostics provide indication of undervoltage, overtemperature, and power bridge faults and can be configured to protect the power MOSFETs under most short circuit conditions.

Fault conditions are indicated by the nFAULT pin. Sign Up 3-phase BLDC sensorless start-up and commutation Gate drive for N-channel MOSFETs Integrated PWM current limit 7 to 50V supply voltage operating range Compatible with 3.3V and 5V logic Cross-conduction 3 Phase Brushless Dc Motor Controller The device is intended to drive a three-phase brushless-DC motor, although it can also be used to drive solenoids or other loads. Bldc Motor Controller Circuit Diagram An automatic internal bootstrap charge management scheme ensures that the bootstrap capacitor is always sufficiently charged for safe operation of the power MOSFETs.

In addition to this enhanced automotive version, Allegro offers a commercial grade, “S” temperature range version of the A4960, A4960SJPTR-T. http://linuxcrypt.net/dc-motor/brushless-driver-motor.html Each output driver channel consists of N-channel power MOSFETs configured in a 1/2-H-bridge configuration.
