International Rectifier IRS260xD family of single-phase high voltage ICs

International Rectifier has released the IRS260xD family of single-phase high voltage ICs for motor drive applications including air conditioners, fans, pumps, micro, mini and general purpose inverter drives.

These power Mosfet and IGBT drivers offer optional dependent or independent high- and low-side referenced output channels with a gate drive supply range from 10V to 20V.

The output drivers feature a high-pulse current buffer stage designed for minimum driver cross-conduction while the floating channel can be used to drive N-channel power Mosfets or IGBTs in the high-side configuration operating up to 600V.

The devices provide matched propagation delay for both channels and an advanced input filter to improve noise immunity in addition to negative voltage spike immunity to protect the system against catastrophic events during high-current switching and short circuit conditions.

The IRS2607D high- and low-side driver features outputs in phase with inputs and is suitable for both trapezoidal and sinusoidal motor control.

The IRS2608D and IRS2609D half-bridge drivers feature internal 540ns dead-time. 

The IRS260xD features under-voltage lock-out protection, integrated deadtime protection, shoot-through protection, a shutdown input and is compatible with 3.3V input logic.
