MC34GD3000 Overview
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.
MC34GD3000 Key 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 transient voltage spikes on the gate driver
- Current shoot-through protection built into dead time control
- Supports direct 3.3 V and 5.0 V logic interface to MCUs
- Integrated current sensing amplifier
