Figures 1 and 2 show the definition of some of the relevant parameters associated with the gate driver output functionality. The output current that drives the gate of the external power switches is defined as IO. The output voltage that drives the gate of the external power switches is defined as VHO for the high side and VLO for the low side; this parameter is sometimes generically called VOUT and in this case the high side and low side output voltages are not differentiated.

The definitions of some of the relevant parameters associated with the gate driver input to output transmission are given. LIN or HIN 50% PWIN 50% t ON tR 90% 10% PWOUT tOFF 90% tF LO or HO 10% Figure 3: Switching time waveforms During interval A of Figure 4 the HVIC receives the command to turn on both the high and low side switches at the same time; correspondingly, the shoot-through protection prevents the high and low side signals HO and LO turn on by keeping them low. Figure 4: Input/output timing diagram Deadtime The IRS2334 HVIC provides an integrated deadtime protection circuitry. The deadtime interval for this HVIC is fixed; while other ICs within IR’s HVIC portfolio feature programmable deadtime for greater design flexibility. The deadtime feature inserts a time interval in which both the gate driver outputs LO and HO are held off; to ensure that the power switch being turned off has fully turned off before the second power switch is turned on. This minimum deadtime is automatically inserted whenever the external deadtime commanded by the host microcontroller is shorter than DT, while external deadtimes larger than DT are not modified by the gate driver. Figure 7 illustrates the deadtime interval definition and the relationship between the output gate signals. www.irf.com © 2010 International Rectifier 13 IRS2334SPbF/MPbF The deadtime interval introduced is matched with respect to the commutation from HIN turning off to LIN turning on, and viceversa. Figure 5 defines the two deadtime parameters DT1 and DT2. The deadtime matching parameter MDT is defined as the maximum difference between DT1 and DT2. LIN HIN 50% LO HO 50% DT1 50% DT2 50% Figure 5: Deadtime definition Matched Propagation Delays The IRS2334 HVIC is designed for propagation delay matching. With this feature, the input to output propagation delays tON, tOFF are the same for the low side and the high side channels; the maximum difference being specified by the delay matching parameter MT as defined in Figure 6. Figure 6: Delay Matching Waveform Definition Input Logic Compatibility The IRS2334 HVIC is designed with inputs compatible with standard CMOS and TTL outputs with 3.3 V and 5 V logic level signals. Figure 7 shows how an input signal is logically interpreted. www.irf.com © 2010 International Rectifier 14 IRS2334SPbF/MPbF Figure 7: HIN & LIN input thresholds Shoot-Through Protection The IRS2334 is equipped with a shoot-through protection circuitry which prevents cross-conduction of the power switches. Table 1 shows the input to output relationship in the form of a truth table. Note that the HVIC has noninverting inputs (the output is in-phase with the respective input). HIN 0 0 1 1 LIN 0 1 0 1 HO 0 0 1 0 LO 0 1 0 0 Table 1: Input/output truth table Under-Voltage Lockout Protection The IRS2334 HVIC provides under-voltage lockout protection on both the VCC low side and logic fixed power supply and the VBS high side floating power supply. Figure 8 illustrates this concept by considering the VCC (or VBS) plotted over time: as the waveform crosses the UVLO threshold, the under-voltage protection is entered or exited. Upon power up, should the VCC voltage fail to reach the VCCUV+ threshold, the gate driver outputs LO and HO will remain disabled. Additionally, if the VCC voltage decreases below the VCCUV- threshold during normal operation, the under-voltage lockout circuitry will shutdown the gate driver outputs LO and HO. Upon power up, should the VBS voltage fail to reach the VBSUV threshold, the gate driver output HO will remain disabled. Additionally, if the VBS voltage decreases below the VBSUV threshold during normal operation, the undervoltage lockout circuitry will shutdown the high side gate driver output HO. The UVLO protection ensures that the HVIC drives external power devices only with a gate supply voltage sufficient to fully enhance them. Without this protection, the gates of the external power switches could be driven www.irf.com © 2010 International Rectifier 15 IRS2334SPbF/MPbF with a low voltage, which would result in power switches conducting current while with a high channel impedance, which would produce very high conduction losses possibly leading to power device failure.

The 1st line shows that for VCC below the UVLO threshold both the gate driver outputs LO and HO are disabled. After VCC returns above VCCUV, the gate driver outputs return functional. The 2nd line shows that for VBS below the UVLO threshold, the gate driver output HO is disabled. After VBS returns above VBSUV, HO remains low until a new rising transition of HIN is received. The last line shows the normal operation of the HVIC. VCC UVLO VCC UVLO VBS Normal operation
