What the 3A peak output means for your power stage
The IR2010SPBF is a half-bridge gate driver rated for 3A peak source and 3A peak sink current, which means it can charge and discharge the gate capacitance of a large IGBT or power MOSFET in the 10-15 ns range — fast enough to keep switching losses low in a 100-200 kHz SMPS or motor-drive inverter without needing an external booster stage.
Supply rails and bootstrap headroom
Operating from a 10V to 20V single supply, the driver's high-side floating channel supports a bootstrap voltage up to 200V — this covers the DC bus of a 120V or 160V motor drive and leaves margin for the bootstrap diode drop and the high-side supply ripple. The logic input thresholds are set at 6V (VIL) and 9.5V (VIH), so the driver accepts 3.3V or 5V logic directly only if the signal swings above 9.5V — in practice, a level-shifter or a 12V gate-drive transformer output is needed to guarantee the VIH threshold.
Package, temperature grade, and compliance
Housed in a 16-SOIC wide-body (0.295-inch, 7.50mm width) surface-mount package, supplied in tube. The operating junction temperature range is -40°C to 150°C, which qualifies it for industrial and automotive under-hood environments where the ambient can reach 105°C and the die sees self-heating from the 3A gate drive.
