Dual-Channel 4A Gate Driver Packs Protection

STMicroelectronics’ STGAP2DM gate driver embarks as the second in the STGAP2 series of galvanically isolated drivers. The device integrates low-voltage control and interface circuitry with two isolated output channels that allow either unipolar or bipolar gate driving.


Rated up to 1700V, built-in isolation enhances safety as well as simplifying design and saving bill of materials and board space. The two 26V rail-to-rail outputs with 4A gate-drive capability ensure reliable performance in industrial motor drives and high-power inverters. The STGAP2DM is also viable for battery chargers, welders, induction heaters, and general-purpose power supplies, and converters.

Integrated include shutdown and brake pins, under-voltage lockout, interlocking to prevent both outputs being high at the same time, and thermal shutdown. A standby mode, controlled by managing voltages on the input pins, lets users save power when the driver is idle. Additionally, the 3.3V/5V TTL/CMOS logic-compatible inputs allow connection to a host controller, and an input-to-output propagation delay of 80 ns ensures fast operation with high PWM-control accuracy.


The STAGP2DM is in production now, packaged as a compact SO-16 device. Prices start from $2.17 each/1,000 pieces. For further information, view the STAGP2DM datasheet.
