Bridge type motor driver for AGV

The invention discloses a bridge type motor driver for an AGV. The bridge type motor driver includes a bridge type driving module, an over-current detection module, a status display module, an emergency power off module, a power conversion module, a single-chip microcomputer and a communication module, wherein the bridge type driving module is used for driving an AGV motor; the over-current detection module is used for real-time sampling and detection of an output current of the bridge type driving module and over-current determination; the status display module is used to display an operatingstatus of an AGV system; the emergency power off module is used to disconnect the bridge type driving module and the motor during overcurrent; the power conversion module is used to supply power to other modules; the communication module is used to implement communication between the bridge type motor driver and an AGV master controller. According to the bridge type motor driver, an NMOS is adopted to construct an H-brid
