Working Principles

The IR2117STR operates by receiving input signals from a microcontroller or other control circuitry. It generates the necessary gate drive voltages to switch the high-side and low-side power switches. The bootstrap supply voltage is used to provide the required voltage level for the high-side gate driver.

When the input signals change state, the IR2117STR quickly adjusts the gate drive voltages to turn on/off the power switches, allowing the desired current flow through the load. The under-voltage lockout and over-current protection features ensure safe operation and protect the circuit components.
