MPC17517中文资料0.46 Ohm (TYP) 3-PHASE BRIDGE MOTOR DRIVER数据手册恩XP规格书

描述 Description

Overview
The MPC17517 is a monolithic 3-Phase Bridge Brushless DC-motor driver that is ideal in portable electronic applications to control small BLDC motors such as Camera Lens Shutters and Optical Disk drives (MO drive, DVC, CD, etc.) MPC17517 is 2.0 ? 6.8 V H-bridge motor driver with enable and tri-state bridge control via a parallel MCU interface (3 and 5 V compatible logic). The IC can drive various types of micro motors with low loss via parallel drive because each section has very efficient drivers designed for PWM Control frequency up to 200 kHz for high speed drive and independent input/output circuitry.
The MPC17517 has Low ON-Resistance of 0.6 Ohm(max). The IC has an integrated charge pump and level shifter (for gate drive voltages). Additionally, the IC has a built in Shoot through current protection circuit and undervoltage detector to avoid malfunction. This IC has 4 output control modes: Forward, Reverse, Brake, Tri-state (Open).
