The MC34937APEK from NXP Semiconductors is a field-effect transistor (FET) pre-driver IC utilizing SMARTMOS technology. It is engineered for three-phase motor control applications, including brushless DC (BLDC) and permanent magnet synchronous motors (PMSM).
This IC features an extended supply voltage operating range from 6.0 V to 58 V and offers a gate drive capability of 1.0 A to 2.5 A. It supports a wide deadtime range, programmable via an SPI port, from 50 ns to 12 µs. The device includes integrated overcurrent, desaturation, and phase fault detection, along with shoot-through protection.
Designed for surface mounting, the MC34937APEK comes in a 54-pin SOIC-EP package. It interfaces with MCUs via direct input control signals and an SPI port, accepting both 3.3 V and 5.0 V logic level inputs and providing 5.0 V logic level outputs. Its applications span various industries, including e-bikes, industrial fans, and portable power tools.
Key features include a charge pump for sufficient external FET drive at low supply voltages and immunity against transient voltage spikes on the gate driver. The device also incorporates an integrated current sensing amplifier for diagnostics and configuration through the SPI port.
