The IR2182S is a monolithic high and low side gate driver that is often used in SMPS (switched mode power supplies). It is designed to drive power MOSFETS, IGBTs, and other power switches. It incorporates two independent high side and low side drivers in a single package rated at 3.2A per driver. The IR2182S is designed to operate from a supply voltage range of 2.7V to 20V and can produce a switching frequency up to 500kHz. It features integrated high side and low side FET short-circuit current limit and thermal shutdown protection, as well as a fault output flag for power supply and thermal overload faults.

Typical applications of the IR2182S include motor control, battery charging, power management and high power DC-DC converters, half bridge and full bridge applications.

The IR2182S is designed to be used in a wide variety of applications, from simple low side drivers to complex three-phase motor control systems. The low side driver section has an independent transformer coupled driver output with a common switching threshold to minimize voltage differences. The high side driver section features an independent high side driver with independently adjustable thresholds. The high side driver also has integrated protection features, such as short-circuit protection, thermal shutdown and a fault output flag.

The IR2182S is designed to ensure the correct operation of the FET by controlling the gate drive waveform. The waveform is generated by a pulse width modulator (PWM) which is triggered by a control voltage input that varies according to the required power level. The waveform is then amplified by the high side and low side drivers which drives the FET gate.

In addition, the IR2182S also has adjustable slow turn-on, fast turn-on, and slow turn-off times. This allows the driver to provide a smooth transition from one operating state to another, providing improved efficiency and EMI performance. All of these features make the IR2182S an ideal choice for high power switching applications.

The IR2182S is a versatile and reliable gate driver for a variety of applications. It combines high power MOSFET gate drive and protection features into a single package, making it an economical and efficient solution for a wide range of power switching applications.
