STMicroelectronics STDRIVE601 BLDC high-voltage gate driver

The STDRIVE601 is a high voltage device manufactured with BCD6s offline technology. It is a single-chip with three half-bridge gate drivers for N-channel power MOSFETs or IGBTs suitable for 3-phase applications. All device outputs can sink and source 350 mA and 200 mA respectively. Prevention from cross-conduction is ensured by interlocking and deadtime function.

EVALSTDRIVE601

• The EVALSTDRIVE601 demonstration board is a complete 3-phase inverter which allows evaluating all of the STDRIVE601 features. The power stage features STGD6M65DF2 IGBTs but can be populated with any IGBT or power MOSFET in DPAK or powerFLAT 8 x 8 HV package. The board is designed to support a three-shunt or a single-shunt current sensing topology.
