IRS2453(1)D(S)
Description
The IRS2453(1)D is based on the popular IR2153 self-oscillating half-bridge gate driver IC, and incorporates a
high voltage full-bridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer.
HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The output driver
features a high pulse current buffer stage designed for minimum driver cross-conduction. Noise immunity is
achieved with low di/dt peak of the gate drivers, and with an undervoltage lockout hysteresis greater than 1.5 V.
The IRS2453(1)D also includes latched and non-latched shutdown pins.

It is recommended to avoid output switching conditions where negative-going spikes at the VS node would
decrease VS below ground by more than -5V.
Enough current should be supplied to the VCC pin of the IC to keep the internal 15.6 V zener diode
clamping the voltage at this pin.

Functional Description
Under-Voltage Lock-Out Mode (UVLO)
The under-voltage lockout mode (UVLO) is defined as the state the IC is in when VCC is below the turn-on
threshold of the IC. The IRS2453(1)D under-voltage lock-out is designed to maintain an ultra low supply current
of less than 150 μA, and to guarantee the IC is fully functional before the high and low side output drivers are
activated. During under-voltage lock-out mode, the high and low side driver outputs LO1, LO2, HO1, HO2 are all
low. With VCC above the VCCUV+ threshold, the IC turns on and the output begin to oscillate.
Normal Operating Mode
Once VCC reaches the start-up threshold VCCUV+, the MOSFET M1 opens, RT increases to approximately VCC
(VCC-VRT+) and the external CT capacitor starts charging. Once the CT voltage reaches VCT- (about 1/3 of VCC),
established by an internal resistor ladder, LO1 and HO2 turn on with a delay equivalent to the deadtime (td).
Once the CT voltage reaches VCT+ (approximately 2/3 of VCC), LO1 and HO2 go low, RT goes down to
approximately ground (VRT-), the CT capacitor starts discharging and the deadtime circuit is activated. At the
end of the deadtime, LO2 and HO1 go high. Once the CT voltage reaches VCT-, LO2 and HO1 go low, RT goes
to high again, the deadtime is activated. At the end of the deadtime, LO1 and HO2 go high and the cycle starts
over again.
The frequency is best determined by the graph, Frequency vs. RT, page 3, for different values of CT. A first
order approximate of the oscillator frequency can also be calculated by the following formula::
1
f ≈
1.453 × RT × CT
This equation can vary slightly from actual measurements due to internal comparator over- and under-shoot
delays.
Bootstrap MOSFET
The internal bootstrap FET and supply capacitor (CBOOT) comprise the supply voltage for the high side driver
circuitry. The internal boostrap FET only turns on when the corresponding LO is high. To guarantee that the
high-side supply is charged up before the first pulse on HO1 and HO2, LO1 and LO2 are both on when CT
ramps between zero and 1/3*VCC. LO1 and LO2 are also on when CT is grounded below 1/6*VCC to ensure that
the bootstrap capacitor is charged when CT is brought back over 1/3*VCC.
Non-Latched Shutdown
If CT is pulled down below VCTSD (approximately 1/6 of VCC) by an external circuit, CT doesn’t charge up and
oscillation stops. All outputs are held low and the bootstrap FETs are off. Oscillation will resume once CT is able
to charge up again to VCT-.
Latched Shutdown
When the SD pin is brought above 2 V, the IC goes into fault mode and all outputs are low. VCC has to be
recycled below VCCUV- to restart the IC. The SD pin can be used for over-current or over-voltage protection using
appropriate external circuitry.
