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.

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.

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.

Some Static Electrical Characteristics are different for the IR2011 and the IRS2011
HVICs. 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)
