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.
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 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. The following equation provides the oscillator frequency:

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. 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.
+ AC Rectified Line
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-.

Fig. 2 Charge pump circuit 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.
