MC34937APEK

Motor driver, 3 Phase FET pre-driver, >1.5A gate drive, FET protection, 58V, SPI, SOIC-EP 54; ? Extended supply voltage operating range: 6.0 to 58 V\n? Wide dead time range (50 ns to 12 μs) programmable via the SPI port\n? External FET gate drive capability of >1.0 A with protection\n? Charge pump ensures sufficient external FET drive at low supply voltages\n? Device protection against reverse charge-injection from CGD and CGS of external FETS\n? Integrated overcurrent, desaturation, and phase fault-detection\n? Immunity against positive or negative transient voltage spikes on the gate driver\n? Current shoot-through protection built into dead time control\n? Supports direct 3.3 V and 5.0 V logic interface to MCUs\n? Integrated current sensing amplifier\n? Device configuration and diagnostics through the SPI\n;

The NXP? MC34937A is a field effect transistor (FET) pre-driver designed for three-phase motor control and similar applications.\nThe integrated circuit (IC) uses SMARTMOS? technology\nThe IC contains three high side FET pre-drivers and three low side FET pre-drivers\nThree external bootstrap capacitors provide gate charge to the high side FETs\nThe 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\nBoth 5.0 and 3.0 V logic level inputs are accepted and 5.0 V logic level outputs are provided\n
