ATA6026 - H-bridge Motor Driver

Description

The ATA6026 is used to drive a continuous-current motor in a full H-bridge configuration.

Features

  • PWM and Direction-controlled Driving of Four Externally Powered NMOS Transistors.
  • Internal Charge Pump Provides Gate Voltages for High-side Drivers in Permanent ON Mode and Supplies the Gate of the External Battery Reverse Protection NMOS.
  • 5V Regulator With External Power Device (NPN) and Current Limitation Function.
  • Reset Derived From 5V Regulator Output Voltage.
  • Sleep Mode With Supply Current of Typical 35 µA, Wake-up by Signal on Pin EN or on.
