The IRS2153(1)D under voltage lock-out is designed to maintain an ultra low supply current of less than 170 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 HO and LO are both low. Supply voltage + AC Rectified Line RVCC VCC 8 RT 2 RT CT 3 CVCC CT COM 4 IRS2153(1)D 1 7 6 VB CBOOT MHS HO L VS 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: RL 5 MLS LO f ~ 1 1.453 × RT × CT - AC Rectified Line 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 IRS2153(1)D 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 0.1 uF. It will be necessary for RVCC to dissipate around 1 W. 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. + AC Rectified Line RVCC RT 2 RT CT CVCC 3 CT COM 8 1 4 IRS2153(1)D VCC 7 VB CBOOT HO MHS DC2 6 L VS CVS 5 LO RL MLS DC1 - AC Rectified Line 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. 9 19 100 18.8 98 Frequency (kHz) Frequency (kHz) IRS2153(1)D 18.6 18.4 96 94 92 18.2 90 -25 18 11 12 13 14 15 0 25 16 50 75 100 125 Temperature(C) VCC(V) FREQ vs VCC FREQ vs TEMP Fig. 4 1.25 1.3 1.15 1.2 1.05 DT(uS) DT(uS) Fig. 3 1.4 1.1 0.95 0.85 1 0.9 11 12 13 14 15 16 0.75 -25 0 25 50 75 100 125 Temperature(C) VCC(V) DT vs TEMP DT vs VCC Fig. 5 (IRS2153D) Fig. 6 (IRS2153D) 17 90 80 VCC (V) Temperature(C) 70 60 50 40 16 30 20 10 15 0 -25 20 70 120 Frequency(kHz) 0 25 50 75 100 125 Temperature (°C) VCC CLAMP vs TEMP Tj vs. Frequency (SOIC) Fig. 7 Fig. 8 10 IRS2153(1)D 300 300 200 150 IsinkLO 250 IsinkHO LO Current (mA) HOCurrent (mA) 250 IsourceHO 100 200 150 IsourceLO 100 50 50 0 -25 0 25 50 75 100 0 -25 125 0 25 Temperature(C) 50 75 100 125 Temperature(C) IsourceHO,IsinkHO vs Temp IsourceLO,IsinkLO vs Temp Fig. 9 Fig. 10 80 VOH_HO vs. Frequency With External BS diode IB_CAP 60 50 16 40 14 VOH_HO (V) IBS_10V 20 10 0 -25 No external BS diode 12 30 0 25 50 75 100 10 8 6 4 125 2 Temperature(C) 0 0 IBCAP, IBS10V vs TEMP 50 100 T=25°C, VS=0V, CHO = 1nF Fig. 11 150 200 250 300 350 400 Frequency (kHz) Fig. 12 VOH_HO vs .
