Three phase field effect transistor

pre-driver

34GD3000

Industrial

The 34GD3000 is a field effect transistor (FET) pre-drivers designed for three

phase motor control and similar applications. The integrated circuit (IC) uses

SMARTMOS technology.

THREE PHASE PRE-DRIVER

The IC contains three high-side FET pre-drivers and three low-side FET pre-

drivers. 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 V

and 3.3 V logic level inputs are accepted and 5.0 V logic level outputs are

provided.

Features

• Extended supply voltage operating range: 6.0 V to 60 V

• Wide dead time range (50 ns to 12 μs) programmable via the SPI port

• Gate drive capability of 1.0 A to 2.5 A

EP SUFFIX (Pb-FREE)

56-PIN QFN

• Charge pump ensures sufficient external FET drive at low supply voltages

• Device protection against reverse charge-injection from C_GDand C_GSof

external FETS

• Integrated overcurrent, desaturation, and phase fault-detection

• Immunity against positive or negative transient voltage spikes on the gate

driver

Applications

• 12 V - 48 V 3-phase brushless DC (BLDC) motors

and permanent magnet synchronous motors (PMSM)

• Pool pumps, hospital beds, electric scooters

• Industrial robotics, pumps and fans

• Portable power tools, commercial fans/blowers

• Small kitchen appliances

• 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

• Device configuration and diagnostics through the SPI
