UPD16814 Datasheet Monolithic Dual H-bridge Driver

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD16814 MONOLITHIC DUAL H BRIDGE DRIVER.

General Description

The µPD16814GS is a monolithic dual H bridge driver circuit employing a power MOS FET for its driver stage.

By plementing the P channel and N channel of the output stage, the circuit current is substantially improved as pared with that of the conventional charge pump driver.

Because the dual H bridge driver circuits at the output stage are independent of each other, this IC is ideal as the driver circuit for a 1- to 2-phase excitation bipolar driving stepping motor for the head actuator of an FDD.

Key Features

  • Low ON resistance (sum of ON resistance of top and bottom FETs) RON1 = 2.0 Ω TYP.
  • Low current consumption: IDD = 100 µA MAX.
  • Four input modes independently controlling dual H bridge drivers.
  • Stop and Brake modes selectable.
  • Surface-mount mini-mold package: 16-pin plastic SOP (300 mil) PIN.
