500 V bootstrap — the application ceiling
The IR2110 is a high-voltage half-bridge gate driver rated for a bootstrap supply up to 500 V on the high side. That 500 V ceiling sets the bus voltage limit for motor drives, UPS inverters, and switch-mode power supplies where this driver sits between the PWM controller and the IGBT or N-Channel MOSFET power stage. Two independent channels, each capable of 2 A peak source and sink current, give the IR2110 the drive strength to switch large-gate-charge devices through the 25 ns rise and 17 ns fall times typical at the output.
Supply and logic interface
The logic input thresholds — VIL at 6 V, VIH at 9.5 V — are referenced to the driver's own VSS, not the controller supply, so the interface needs a clean ground return between the two.
No official successor is listed on the record.
Supplied in a 14-lead DIP (0.300-inch body, 7.62 mm pitch) with through-hole mounting — the same footprint as the industry-standard IR2110 family.
