Gate drivers are a type of power management integrated circuits (PMICs) which provide precision control over the gate signals of power MOSFET and IGBT transistors. The IR2122 is a gate driver IC and is used to drive high voltage, high current MOSFETs and IGBTs. It amplifies the gate control signal, allowing the low current input pins to control a large and sometimes indeterminate load.
The IR2122 is a dual-channel gate driver IC, suitable for driving two MOSFETs/IGBTs simultaneously. It comes with self-standoff terminals, applied to the high voltage side for insulation protection. It has a dual-channel design, which can be used to control two independent power switches. Its fast turn-on and turn-off times aid in fast transfer of charge across the power devices. The IR2122 can provide 6A peak output current and can be powered from a single +12V or +14V supply voltage.
The IR2122 has built in features such as adjustable dead time, current sensing and SmartGate drive capability, which allows it to be used in a wide variety of applications. It is well-suited for switching power converters, DC-to-DC converters, Uninterruptible Power Supplies (UPSs) and high-power motor controls. It is also used in various applications such as LED lighting, solar inverters, industrial automation and automotive powertrain systems.
The IR2122 has a low propagation delay and internal structure with matched rise and fall times, effectively eliminate shoot-through current. Its integrated Low-side Current sensing transformer allows for current sensing with high accuracy from the low-side MOSFET/IGBT gate and increased performance. With SmartGate drive, it helps enhance controller efficiency by reducing the total number of external MOSFETs required. Its fault-tolerant protection feature ensures the device can detect and drive faults.}
The IR2122 operates by amplifying the control signal from the microcontroller, enabling it to drive the MOSFET/IGBT accurately and quickly. Its six independent, self-maintaining high-drive outputs switch the power supply on and off, to control the device, while a low-side MOSFET/IGBT channel can be used to sense the current. The internal dead time block helps in stopping the shoot-through current when switching on/off the supplies and both the low side and high side MOSFET channels can be phase shifted by an adjustable delay.
The IR2122 is an optimal choice for controlling power switches in high power applications, as it combines high performance, precision and efficient control with low operating costs. It is highly reliable, with a wide operational temperature range which makes it suitable for many applications. Its protected design and small form factor make it easy to integrate in any application, helping reduce design complexity and cost.
