Infineon Technologies expands its 200V driver IC portfolio with the IRS2005 (S, M) for high voltage, high speed IGBTs and power MOSFETs. The driver IC features comprehensive protection for motor drive applications with stringent space constraints such as electric garden equipment, golf carts, power tools and mobility scooters.

The IRS200x family consists of high-side & low-side and half bridge drivers utilising Infineon’s proven, robust high-voltage junction isolation (HVJI) technology to realise small packages while remaining tolerant to negative transient voltages. The 200V devices are tailored for low-voltage (24, 36, and 48V) and mid-voltage (60, 80, and 100V) applications. They enable high system level efficiency and power density while providing the necessary robustness.

The IRS200x family consists of six devices with a typical sink current of 600mA and source current of 290mA. The 200V devices are compatible to 3.3, 5, and 15V logic components. Across the family the driver ICs feature VCC Under Voltage Lock Out (UVLO) while the IRS2005 also includes VBS UVLO, further improving system reliability.

The 200V driver ICs are designed for use with bootstrap power supplies which eliminates the need for large and expensive auxiliary power supplies typically needed in discrete optocoupler- or transformer based designs. Additionally, the IRS2003 and IRS2004 include integrated deadtime and shoot-through protection. The 200V devices feature low quiescent currents. The IRS2004 also features a shutdown input pin.
