Description
The IRS2153D is based on the popular IR2153 selfoscillating half-bridge gate driver IC using a more
advanced silicon platform, and incorporates a high
voltage half-bridge gate driver with a front end oscillator
similar to the industry standard CMOS 555 timer. HVIC
and latch immune CMOS technologies enable rugged
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.

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 IRS2153D under voltage lock-out is designed to maintain an
ultra low supply current of less than 155uA, 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 HO and LO are both low.

HO
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 LO is high. To
guarantee that the high-side supply is charged up before the first
pulse on pin HO, the first pulse from the output drivers comes
from the LO pin.
Normal operating mode
Once the VCCUV+ threshold is passed, 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, LO turns on with a delay equivalent to the
deadtime td. Once the CT voltage reaches VCT+ (approximately
2/3 of VCC), LO goes low, RT goes down to approximately
ground (VRT-), the CT capacitor discharges and the deadtime
circuit is activated. At the end of the deadtime, HO goes high.
Once the CT voltage reaches VCT-, HO goes low, RT goes high
again, the deadtime is activated. At the end of the deadtime, LO
goes high and the cycle starts over again.

Fig. 1 Typical Connection Diagram
Fig. 1 shows an example of supply voltage. The start-up
capacitor (CVCC) is charged by current through supply resistor
(RVCC) minus the start-up current drawn by the IC. This resistor is
chosen to provide sufficient current to supply the IRS2153D from
the DC bus. CVCC should be large enough to hold the voltage at
Vcc above the UVLO threshold for one half cycle of the line
voltage as it will only be charged at the peak, typically 0.1uF. It
will be necessary for RVCC to dissipate around 1W.
This equation can vary slightly from actual measurements due to
internal comparator over- and under-shoot delays. For a more
accurate determination of the output frequency, the frequency
characteristic curves should be used (RT vs. Frequency, Page 3).
Shut-down
If CT is pulled down below VCTSD (approximately 1/6 of VCC) by
an external circuit, CT doesn’t charge up and oscillation stops.
LO is held low and the bootstrap FET is off. Oscillation will
resume once CT is able to charge up again to VCT-.
The use of a two diode charge pump made of DC1, DC2 and
CVS (Fig. 2) from the half bridge (VS) is also possible however
the above approach is simplest and the dissipation in RVCC should
not be unacceptably high.

The supply resistor (RVCC) must be selected such that enough
supply current is available over all operating conditions.
Once the capacitor voltage on VCC reaches the start-up
threshold VCCUV+, the IC turns on and HO and LO begin to
oscillate.
