MC34GD3000 - Three phase field effect transistor predriver

Description

The 34GD3000 is a field effect transistor (FET) predriver designed for three phase motor control and similar applications.

It meets the stringent requirements of automotive applications and is fully AEC-Q100 grade 1 qualified.

Features

  • Extended supply voltage operating range: 6.0 V to 60 V.
  • Gate drive capability of 1.0 A to 2.5 A.
  • Device protection against reverse charge-injection from CGD and CGS of external FETs.
  • Includes a charge pump to support full FET drive at low battery voltages.
  • Wide dead time range (50 ns to 12 µs) programmable via the SPI port.
  • Integrated overcurrent, desaturation, and phase fault-detection.
  • Immunity against positive or negative transie.

MC34GD3000 Three phase field effect transistor predriver Rev. 7.0 — 16 March 2022 Product data sheet 1 General description The 34GD3000 is a field effect transistor (FET) predriver designed for three phase motor control and similar applications. It meets the stringent requirements of automotive applications and is fully AEC-Q100 grade 1 qualified. The IC contains three high-side FET predrivers and three low-side FET predrivers. Three external bootstrap capacitors provide gate charge to the high-side FETs. The IC interfaces to a MCU via six direct input control signals, an SPI port for device setup and asynchronous reset, enable and interrupt signals. Both 5.0 and 3.3 V logic level inputs are accepted and 5.0 V logic level outputs are provided.
