Working Principles

The IR21141SSTRPBF operates by receiving a logic input signal (IN) that controls the gate driver's output stages. The high-side and low-side outputs (HO and LO) provide the necessary drive signals to control the power device's gate voltage. The integrated bootstrap diode (VB) simplifies the high-side gate drive circuitry by generating the required voltage from the low-side supply.

The UVLO protection ensures that the gate driver operates within the specified voltage range, preventing damage to the IC and power devices. The over-current and short-circuit protection features safeguard against excessive current flow and potential device failure. The fault reporting output provides an indication of any detected faults or abnormal conditions.
