| Application Note AN-1097 IRS2011 and IR2011 Comparison By Jason Nguyen, Min Fang, David New Table of Contents Page Introduction ..........................................................................................1 Block Diagram......................................................................................2 Electrical Characteristic Differences.....................................................3 Figures .................................................................................................3 Summary..............................................................................................9 Introduction The IRS2011 is a new HVIC product that replaces the IR2011 and is pin-to-pin compatible with its predecessor. This application note describes the various differences between the IRS2011 and the IR2011 HVICs. The IRS2011 is a high power, high speed power MOSFET driver with independent high and low side referenced output channels, ideal for Class D Audio and DC-DC converter applications. Logic inputs are compatible with standard CMOS or LSTTL outputs, down to 3.0 V logic. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. Propagation delays are matched to simplify its use in high frequency applications. The floating channel can be used to drive an N-channel power MOSFET in the high side configuration which operates up to 200 V. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. www.irf.com AN-1097 1 Block Diagram The IRS2011 and IR2011 share the same block diagram. The functionality of the two ICs is the same. Electrical Characteristic Differences All measurement conditions remain unchanged unless noted. Parameters not mentioned have not changed. Absolute Maximum Ratings Symbol VB VS VCC Parameter Definition High side floating supply voltage High side floating supply offset voltage Low side fixed supply voltage IR2011 min -0.3 VB - 25 -0.3 max 225 VB + 0.3 25 IRS2011 min max -0.3 VB - 20 -0.3 220 (Note1) VB + 0.3 20 (Note1) Units V Note1: In the IRS2011, all supplies are fully tested at 25 V and an internal 20 V clamp exists for each supply. The 20 V, internal clamp improves the IC survivability against supply transient spikes but at the same time reduces the absolute maximum rating to 20 V. Recommended Operating Conditions The minimum VS is changed from -4 V (IR2011) to -5 V (IRS2011), which increases the VS negative voltage capability by 1 V. www.irf.com AN-1097 2 Dynamic Electrical Characteristics Symbol ton toff tr tf Parameter Definition Turn-on propagation delay (Vs = 0 V) Turn-off propagation delay (Vs = 200 V) Turn-on rise time Turn-off fall time IR2011 typ 80 75 35 20 max 50 35 IRS2011 typ max 60 60 25 15 80 80 Units ns 40 35 The IRS2011 has reduced in propagation delays and faster rise/fall times when compared to the IR2011.

With the IRS2011, 1. VIH is increased to 2.5 V for better noise immunity yet still maintains 3.3 V logic compatibility. 2. Both IQCC and IQBS have increase slightly. 3. The IIN+ has been reduced for the IRS2011. 4. The VCC and VBS under voltage thresholds (max and min) show a slight difference between the two devices. This is not expected to have an impact on many designs. Figures This figures shown in this section compare figures shown in the IR2011 (left column) and IRS2011 (right column) datasheets. Illustrations that have not changed between the two datasheets have not been included in this section. www.irf.com AN-1097 3 IR2011 Turn-on Propagation Delay (ns) 500 400 300 200 100 Typ.
