描述 Description

The NXP® MC34937A is a field effect transistor (FET) pre-driver designed for three-phase motor control and similar applications.
The integrated circuit (IC) uses SMARTMOS® technology
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, a SPI port for device setup and fault detection, an asynchronous reset, an interrupt and two enable signals
Both 5.0 and 3.0 V logic level inputs are accepted and 5.0 V logic level outputs are provided

特性 Features

• Extended supply voltage operating range: 6.0 to 58 V
• Wide dead time range (50 ns to 12 μs) programmable via the SPI port
• External FET gate drive capability of >1.0 A with protection
• Charge pump ensures sufficient external FET drive at low supply voltages
• Device protection against reverse charge-injection from CGD and CGS of external FETS
• 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
• Device configuration and diagnostics through the SPI
