4. VCC(min) = VCCreset

5. Outputs Lgs and Hgs (pin 9/10) are unloaded.

6. Guaranteed by design.

7. DCsh = (DChs/(DChs + DCls)) * 100%, DCsl = (DCls/(DChs + DCls)) * 100%

8. The VFB_DC_0 is the FB voltage below which are all outputs disabled.

The FB voltage has to increases to VFB_DC_0 + VFB_DC_0_Hyste to re−enable all outputs of the controller.

9. Low impedance source and sink RDS(on) are designed to respectively deliver 0.5 A and −1 A at Tj = 100°C.

10. Pins 17, 18 and 19 are on the same potencial during IHV_LEAK measurements

11. On−time on synchro outputs wont be longer than on−time on power outputs.

12. The soft start pin is pulled down by an internal switch until the CIG timer ending voltage is reached

13. FB timer is disabled until the soft−start ending voltage is reached

14. EN1 input is blanked until the preheat period (CIG) ends. The OTP input is blanked during full startup sequence made of: PFC_del + CIG_t + SS_t

15. The FB timeout circuit starts to operate at the end of PFC_del + CIG_t + SS_t period.

16. An NTC resistor of 8.8 kW @ TA = 110°C is connected to ground.

17. The EN1 and EN2 input voltages have to go 50 mV below VEN1, VEN2 to release these inputs.

18. The OTP input voltage has to go 50 mV above OTPref_V to release this input.

19. The R_Fmin pin do not accept any bypass capacitor

20. Maximum acceptable capacitance connected to the pin is 100 pF

21. Measured for VCC = 10.5 V
