IR2110 Pinout: Evaluation and Analysis

IR2110 pinout in PDIP IC architecture

The days when you could fix pretty much everything on your car in the backyard with a modest assortment of screwdrivers and sockets are a distant memory. Vehicles today may contain as many as a few thousand microchips. These components enable the design of automotive systems with ever increasing functionality that translates into more comfortable, reliable, and safer transportation for drivers and passengers.

Many of the ICs in automotive systems are transistors; including MOSFETs and insulated-gate bipolar transistors (IBGTs). An important aspect of employing these devices is the driving circuitry. An integrated monolithic HVIC driver for high-speed, high-voltage, dual-channel operation that has proven to be very successful for automotive applications is the IR2110. By examining the IR2110 pinout and component characteristics you will be able to best use this IC module in your design.

The IR2110 Pinout

The IR2110, manufactured by Infineon Technologies comes in two common IC package options: plastic dual in-line package (PDIP) and small outline integrated circuit (SOIC) package. The IR2110 pinouts for these package types, are shown below.

IR2113 and IR2110 pinouts for PDIP and SOIC packages

As indicated above, the IR2113, which is a faster switching device for higher voltage applications, has the same pin designations as the IR2110. From the IR2110 datasheet, the pin descriptions are listed in the table below for both package types.

IR2110 PINOUT SPECIFICATIONS
Label	Pin No. PDIP\|SOIC	Description
LO	1\|1	Low side gate drive output
COM	2\|2	Low side return
VCC	3\|3	Low side supply
VS	5\|6	High side floating supply return
VB	6\|7	High side floating supply
HO	7\|8	High side gate drive output
VDD	9\|11	Logic supply
HIN	10\|12	Logic input for high side gate driver output (HO), in phase
SD	11\|13	Logic input for shutdown
LIN	12\|14	Logic input for low side gate driver output (LO), in phase
VSS	13\|15	Logic ground

As listed, both devices have both a low and high side input and output. For the IR2110, the high side max voltage is 500V. For the IR2113, this voltage is 600V. These and other important features are given in the section below.
