UCD7232 Datasheet Digital Control Compatible Synchronous-buck Gate Driver

Manufacturer: Texas Instruments

Overview: UCD7232 .ti. SLUSAH3 – MAY 2011 Digital Control patible Synchronous-Buck Gate Driver With Current Sense and Fault Protection Check for Samples:.

General Description

The UCD7232 high current driver is specifically designed for digitally-controlled, point-of-load, synchronous buck switching power supplies.

Two driver circuits provide high charge and discharge current for the high-side NMOS switch and the low-side NMOS synchronous rectifier in a synchronous buck circuit.

The MOSFET gates are driven by an internally regulated VGG supply.

Key Features

  • 1.
  • Dual High Current Drivers.
  • Full Compatibility with TI Fusion Digital Power Supply Controllers, such as UCD91xx and UCD92xx Families.
  • Operational to 2 MHz Switching Frequency.
  • High-Side FET and Output Current Limit Protection with Independently Adjustable Thresholds.
  • Fast High-Side Overcurrent Sense Circuit with Fault Flag Output.
  • Prevents Catastrophic Current Levels on a Cycle-by-Cycle Basis.
  • Differential High-Gain Current Sense.
