AUIRS2181(4)S

Description

The AUIRS2181(4)(S) are high voltage, high speed power MOSFET and IGBT drivers with independent high

and low-side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable

ruggedized monolithic construction. The logic input is compatible with standard CMOS or LSTTL output,

down to 3.3 V logic. The output drivers feature a high pulse current buffer stage designed for minimum driver

cross-conduction. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the

high-side configuration which operates up to 600 V.

Recommended Operating Conditions

The input/output logic timing diagram is shown in figure 1. For proper operation the device should be used

within the recommended conditions. The VS and VSS offset rating are tested with all supplies biased at 15 V

differential.

†† Logic operational for VS of -5 V to +600 V. Logic state held for VS of -5 V to –VBS. (Please refer to the

Design Tip DT97-3 for more details).

††† HIN and LIN are internally clamped with a 5.2 V zener diode.

Absolute Maximum Ratings

Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All

voltage parameters are absolute voltages referenced to COM lead. Stresses beyond those listed under "

Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only;

and functional operation of the device at these or any other condition beyond those indicated in the

“Recommended Operating Conditions” is not implied. Exposure to absolute-maximum-rated conditions for

extended periods may affect device reliability. The thermal resistance and power dissipation ratings are

measured under board mounted and still air conditions. Ambient temperature (TA) is 25°C, unless otherwise

specified.

Parameter Trends vs. Temperature and vs. Supply Voltage

Figures of this chapter provide information on the experimental performance of the AUIRS2181(4)S HVIC.

The line plotted in each figure is generated from actual lab data.

A large number of individual samples were tested at three temperatures (-40 ºC, 25 ºC, and 125 ºC) in order

to generate the experimental curve. The line consists of three data points (one data point at each of the

tested temperatures) that have been connected together to illustrate the understood trend. The individual

data points on the Typ. curve were determined by calculating the averaged experimental value of the

parameter (for a given temperature).

A different set of individual samples was used to generate curves of parameter trends vs. supply voltage.
