UPD168302 - MONOLITHIC 2CH H-BRIDGE DRIVER

General Description

The µPD168302 is monolithic dual H-bridge driver LSI which uses power MOS FETs in the output stages.

By using the MOS process, this driver has substantially improved the voltage loss of the output stage and power consumption as compared with conventional driver using bipolar transistors.

Key Features

  • 2ch H-Bridge circuit employing power MOS FETs.
  • Charge-pump circuit for low-voltage operation.
  • Low output FET on resistance: 1.0 Ω TYP. 2.0 Ω MAX. (Sum of upper and lower side).
  • Output current: DC current 0.6 A/ch Peak current 1.0 A/ch.
  • Input logic frequency: 100 kHz.
  • 5 V logic power supply: Minimum operating supply voltage 4.0 V.
  • 0.9 to 3.6 V power supply for motor drive.
  • Under voltage locked out circuit: shutdown internal.

DATA SHEET MOS INTEGRATED CIRCUIT µ PD168302 MONOLITHIC 2CH H-BRIDGE DRIVER DESCRIPTION The µPD168302 is monolithic dual H-bridge driver LSI which uses power MOS FETs in the output stages. By using the MOS process, this driver has substantially improved the voltage loss of the output stage and power consumption as compared with conventional driver using bipolar transistors. As the package, a 24-pin plastic TSSOP is adopted to enable the creation of compact, slim application sets. It is provided with forward/reverse and brake functions and is ideal as a driver for DC motor and stepping motor. FEATURES • 2ch H-Bridge circuit employing power MOS FETs • Charge-pump circuit for low-voltage operation • Low output FET on resistance: 1.0 Ω TYP. 2.0 Ω MAX.
