What is IR2110 :

The IRS2110/IRS2113 are high voltage, high speed

power MOSFET and IGBT drivers with independent

high and low side referenced output channels.

The Chips have several applications like motor drives,

lighting blast, switched mode power supplies,

Automotives, Plasma Display panels.


3/37

Technical Features of IR2110 :

Logic inputs are compatible with standard CMOS orLSTTL output, down to 3.3 V logic.

The floating channel can be used to drive an N-channel

power MOSFET or IGBT in the high side configuration

which operates up to 500 V or 600 V. The IRS2110/IRS2113, has a floating channel which

provides gate drive for the high side switch.

The gate drive supply range is quite wide (10 V to 20

V).


4/37

Design Features of IR2110 :

Floating channel designed for bootstrap operation

Fully operational to +500 V or +600 V

Tolerant to negative transient voltage, dV/dt immune.

Gate drive supply range from 10 V to 20 V.

Undervoltage lockout for both channels.

3.3 V logic compatible.

Separate logic supply range from 3.3 V to 20 V.

Logic and power ground 5 V offset. CMOS Schmitt-triggered inputs with pull-down.

Cycle by cycle edge-triggered shutdown logic.

Matched propagation delay for both channels.

Outputs in phase with inputs.

Theory:

The shutdown function is latched so that the powerMOSFETs will remain in the offstate as the load current

decays through their internal diodes.

The latch is reset at the beginning of next cycle, when

the power devices are once again commanded on. The decoupling capacitors mitigate the negative effects

of L1.

As an added safety margin a resistor diode network can

be added to the gate, as shown in modified circuit withdashed lines.


22/37

Theory(contd)

The purpose of this network is to further delay the turn-on, without affecting the turn-off, thereby inserting some

additional dead-time.

The resistor-diode network is also useful in reducing the

peak of the current spike during the reverse recoverytime.
