MC34GD3000 Three phase field effect transistor Rev. 6.0 27 October 2020 Product data sheet 1 General description 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. 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 and 3.3 V logic level inputs are accepted and 5.0 V logic level outputs are provided. The integrated circuit (IC) uses SMARTMOS technology. 2 Features and benefits 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 C and C of external FETs GD GS Includes a charge pump to support full FET drive at low battery voltages Wide dead time range (50 ns to 12 s) 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 Device configuration and diagnostics through the SPI 3 Applications 12 to 48 V 3-phase brushless DC (BLDC) motors Permanent-magnet synchronous motors (PMSM) Pool pumps, hospital beds, electric scooters Industrial robotics, pumps, fans Portable power tools, commercial fans/blowers Small kitchen appliancesNXP Semiconductors MC34GD3000 Three phase field effect transistor 4 Ordering information Table 1.Ordering information Type number Package Name Description Version MC34GD3000EP HVQFN56 Plastic, thermal enhanced very thin quad flatpack no leads 56 SOT684-17 terminals 0.5 mm pitch 8 mm x 8 mm x 0.9 mm body 5 Block diagram PUMP VPWR VSUP VPUMP MAIN CHARGE TRICKLE HOLD PGND PUMP CHARGE -OFF PUMP CIRCUIT 5.0 V VLS REG.
