Figures 1 and 2 illustrate several parameters associated with the gate drive functionality of the HVIC. The output current of the HVIC, used to drive the gate of the power switch, is defined as IO. The voltage that drives the gate of the external power switch is defined as VHO for the high-side power switch and VLO for the low-side power switch; this parameter is sometimes generically called VOUT and in this case does not differentiate between the high-side or low-side output voltage.

From these figures, we can see the definitions of several timing parameters (i.e., PW IN, PW OUT, tON, tOFF, tR, and tF) associated with this device.

With this feature, the IC’s response at the output to a signal at the input requires approximately the same time duration (i.e., tON, tOFF) for both the low-side channels and the high-side channels; the maximum difference is specified by the delay matching parameter (MT). The propagation turn-on delay (tON) of the IRS2607D is matched to the propagation turn-on delay (tOFF). www.irf.com 8 IRS2607DSPbF Rev22 Figure 5: Delay Matching Waveform Definition Input Logic Compatibility The inputs of this IC are compatible with standard CMOS and TTL outputs. The IRS2607D has been designed to be compatible with 3.3 V and 5 V logic-level signals.

Figure 7 is used to illustrate this concept; VCC (or VBS) is plotted over time and as the waveform crosses the UVLO threshold (VCCUV+/- or VBSUV+/-) the undervoltage protection is enabled or disabled. Upon power-up, should the VCC voltage fail to reach the VCCUV+ threshold, the IC will not turn-on. Additionally, if the VCC voltage decreases below the VCCUV- threshold during operation, the undervoltage lockout circuitry will recognize a fault condition and shutdown the high- and low-side gate drive outputs, and the FAULT pin will transition to the low state to inform the controller of the fault condition. Upon power-up, should the VBS voltage fail to reach the VBSUV threshold, the IC will not turn-on. Additionally, if the VBS voltage decreases below the VBSUV threshold during operation, the undervoltage lockout circuitry will recognize a fault condition, and shutdown the high-side gate drive outputs of the IC. The UVLO protection ensures that the IC drives the external power devices only when the gate supply voltage is sufficient to fully enhance the power devices. Without this feature, the gates of the external power switch could be driven with a low voltage, resulting in the power switch conducting current while the channel impedance is high; this could result in very high conduction losses within the power device and could lead to power device failure. Figure 7: UVLO protection www.irf.com 10 IRS2607DSPbF Rev22 Advanced Input Filter The advanced input filter allows an improvement in the input/output pulse symmetry of the HVIC and helps to reject noise spikes and short pulses. This input filter has been applied to the HIN ans LIN inputs. The working principle of the new filter is shown in Figures 8 and 9. Figure 8 shows a typical input filter and the asymmetry of the input and output. The upper pair of waveforms (Example 1) show an input signal with a duration much longer then tFIL,IN; the resulting output is approximately the difference between the input signal and tFIL,IN. The lower pair of waveforms (Example 2) show an input signal with a duration slightly longer then tFIL,IN; the resulting output is approximately the difference between the input signal and tFIL,IN. Figure 9 shows the advanced input filter and the symmetry between the input and output. The upper pair of waveforms (Example 1) show an input signal with a duration much longer then tFIL,IN; the resulting output is approximately the same duration as the input signal. The lower pair of waveforms (Example 2) show an input signal with a duration slightly longer then tFIL,IN; the resulting output is approximately the same duration as the input signal. Figure 8: Typical input filter Figure 9: Advanced input filter Short-Pulse / Noise Rejection This device’s input filter provides protection against short-pulses (e.g., noise) on the input lines. If the duration of the input signal is less than tFIL,IN, the output will not change states. Example 1 of Figure 10 shows the input and output in the low state with positive noise spikes of durations less than tFIL,IN; the output does not change states. Example 2 of Figure 10 shows the input and output in the high state with negative noise spikes of durations less than tFIL,IN; the output does not change states. Example 2 Figure 10: Noise rejecting input filters www.irf.com Example 1 11 IRS2607DSPbF Rev22 Figures 11 and 12 present lab data that illustrates the characteristics of the input filters while receiving ON and OFF pulses. The input filter characteristic is shown in Figure 11; the left side illustrates the narrow pulse ON (short positive pulse) characteristic while the left shows the narrow pulse OFF (short negative pulse) characteristic. The x-axis of Figure 11 shows the duration of PW IN, while the y-axis shows the resulting PW OUT duration. It can be seen that for a PW IN duration less than tFIL,IN, that the resulting PW OUT duration is zero (e.g., the filter rejects the input signal/noise). We also see that once the PW IN duration exceed tFIL,IN, that the PW OUT durations mimic the PW IN durations very well over this interval with the symmetry improving as the duration increases. To ensure proper operation of the HVIC, it is suggested that the input pulse width for the high-side inputs be ≥ 500 ns. The difference between the PW OUT and PW IN signals of both the narrow ON and narrow OFF cases is shown in Figure 12; the careful reader will note the scale of the y-axis. The x-axis of Figure 12 shows the duration of PW IN, while the yaxis shows the resulting PW OUT–PW IN duration. This data illustrates the performance and near symmetry of this input filter.

A bootstrap FET is connected between the floating supply VB and VCC (see Fig. 13). Vcc BootFet Vb Figure 13: Semplified BootFET connection The bootstrap FET is suitable for most PWM modulation schemes, including trapezoidal control, and can be used either in parallel with the external bootstrap network (diode+ resistor) or as a replacement of it. The use of the integrated bootstrap as a replacement of the external bootstrap network may have some limitations in the following situations: • W hen the motor runs at a very low current (so that the negative phase voltage decay can be longer than 20us) and complementary PWM is not used. • At a very high PWM duty cycle due to the bootstrap FET equivalent resistance (RBS, see page 3). The summary for the bootstrap state follows: • Bootstrap turns-off (immediately) or stays off when at least one of the following conditions are met: 1- HO goes/is high 2- VB goes/is high (> 1.1*VCC) • Bootstrap turns-on when: 1- LO is high (low side is on) AND VB is low (< ~1.1(VCC)) 2- LO and HO are low after a LIN transition from H to L (HB output is in tri-state) AND VB goes low ( 0 In the absence of a VCC bias, the integrated bootstrap FET voltage blocking capability is compromised and a current conduction path is created between VCC & VB pins, as illustrated in Fig.27 below, resulting in power loss and possible damage to the HVIC. www.irf.com 18 IRS2607DSPbF Rev22 Figure 27: Current conduction path between VCC and VB pin Relevant Application Situations: The above mentioned bias condition may be encountered under the following situations: • In a motor control application, a permanent magnet motor naturally rotating while VCC power is OFF. In this condition, Back EMF is generated at a motor terminal which causes high voltage bias on VS nodes resulting unwanted current flow to VCC. • Potential situations in other applications where VS/VB node voltage potential increases before the VCC voltage is available (for example due to sequencing delays in SMPS supplying VCC bias) Application Workaround: Insertion of a standard p-n junction diode between VCC pin of IC and positive terminal of VCC capacitors (as illustrated in Fig.28) prevents current conduction “out-of” VCC pin of gate driver IC. It is important not to connect the VCC capacitor directly to pin of IC. Diode selection is based on 25V rating or above & current capability aligned to ICC consumption of IC - 100mA should cover most application situations. As an example, Part number # LL4154 from Diodes Inc (25V/150mA standard diode) can be used. VCC VCC VCC Capacitor VB VSS (or COM) Figure 28: Diode insertion between VCC pin and VCC capacitor Note that the forward voltage drop on the diode (VF) must be taken into account when biasing the VCC pin of the IC to meet UVLO requirements.
