SM74104 - High Voltage Half-Bridge Gate Driver

General Description

The SM74104 High Voltage Gate Driver is designed to drive both the high side and the low side NChannel MOSFETs in a synchronous buck configuration.

The floating high-side driver is capable of working with supply voltages up to 100V.

Key Features

  • 1 Renewable Energy Grade.
  • Drives both a High Side and Low Side N-Channel MOSFET.
  • Adaptive Rising and Falling Edges with Programmable Additional Delay.
  • Single Input Control.
  • Bootstrap Supply Voltage Range up to 118V DC.
  • Fast Turn-Off Propagation Delay (25 ns Typical).
  • Drives 1000 pF Loads with 15 ns Rise and Fall Times.
  • Supply Rail Under-Voltage Lockout 2 Typical.
