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. www.irf.com © 2007 International Rectifier 3 IRS2453(1)D(S) † Qualification Information Qualification Level Moisture Sensitivity Level Machine Model ESD Human Body Model IC Latch-Up Test RoHS Compliant † †† ††† Industrial†† Comments: This family of ICs has passed JEDEC’s Industrial qualification.

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. 50% HO1 50% td_LO1 td_HO1 LO1 50% 50% ton_LO 50% Deadtime Waveform www.irf.com © 2007 International Rectifier 13 IRS2453(1)D(S) tr tf 90% HO LO 10% Rise and Fall Time Waveform www.irf.com © 2007 International Rectifier 14 IRS2453(1)D(S) Package Details www.irf.com © 2007 International Rectifier 15 IRS2453(1)D(S) Tape and Reel Details LOADED TAPE FEED DIRECTION A B H D F C NOTE : CONTROLLING DIM ENSION IN M M E G CARRIER TAPE DIMENSION FOR Metric Code Min Max A 7.90 8.10 B 3.90 4.10 C 15.70 16.30 D 7.40 7.60 E 6.40 6.60 F 9.40 9.60 G 1.50 n/a H 1.50 1.60 14SOICN Imperial Min Max 0.311 0.318 0.153 0.161 0.618 0.641 0.291 0.299 0.252 0.260 0.370 0.378 0.059 n/a 0.059 0.062 F D C B A E G H REEL DIMENSIONS FOR 14SOICN Metric Imperial Code Min Max Min Max A 329.60 330.25 12.976 13.001 B 20.95 21.45 0.824 0.844 C 12.80 13.20 0.503 0.519 D 1.95 2.45 0.767 0.096 E 98.00 102.00 3.858 4.015 F n/a 22.40 n/a 0.881 G 18.50 21.10 0.728 0.830 H 16.40 18.40 0.645 0.724 www.irf.com © 2007 International Rectifier 16 IRS2453(1)D(S) Part Marking Information www.irf.com © 2007 International Rectifier 17 IRS2453(1)D(S) Ordering Information Standard Pack Base Part Number Package Type PDIP14 IRS2453D(S) IRS24531DS SOIC14N SOIC14N Complete Part Number Form Quantity Tube/Bulk 25 IRS2453DPBF Tube/Bulk 55 IRS2453DSPBF Tape and Reel 2500 IRS2453DSTRPBF Tube/Bulk 55 IRS24531DSPBF Tape and Reel 2500 IRS24531DSTRPBF The information provided in this document is believed to be accurate and reliable.
