Working principle

The IRS2301SPBF is a high-speed, high-current gate driver IC that can drive a wide variety of IGBT, MOSFET, and AC switches. The IC features an input stage with two power inputs and two logic inputs for controlling the gate driver outputs. The inputs can be connected directly to logic circuits, such as microcontrollers and gate drivers, or to signal sources from power control ICs. The IC also features an output stage with two independent outputs. Each output can provide up to 2.6 A of peak current to drive the gate of an IGBT, MOSFET, or AC switch.

The output signals of the IRS2301SPBF can be controlled by the logic inputs or by an internal circuitry that is programmable via external components. The internal circuitry provides a number of protection functions, including under-voltage lockout, over-current protection, thermal shutdown, dead-time insertion, and cross-conduction prevention. These functions help prevent many situations that might damage the semiconductor switches, such as simultaneous conduction of the upper and lower devices, high peak currents during turn-on, and over-temperature conditions.

The IC is packaged in an RoHS compliant DSO-8 package, which is compact and cost-effective. It is suitable for high-volume manufacturing and long-term reliability in automotive and industrial applications.
