13 / 50 page ![]() TDA9113 13/50 Note 11: The threshold for VVOB is generated internally and routed to VOscF pin. Any DC current on this pin will influence the value of VVOB. Note 12: Maximum of deviation from an ideally linear sawtooth ramp at null SCOR (Sad09 at x0000000b) and null CCOR (Sad0A at x1000000b). The same rate applies to V-drive signal on VOut pin. Note 13: Maximum SCOR (Sad09 at x1111111b), null CCOR (Sad0A at x1000000b). Note 14: Null SCOR (Sad09 at x0000000b). Note 15: ”tVR” is time from the beginning of vertical ramp of V-drive signal on VOut pin. ”TVR” is duration of this ramp, see chapter TYPICAL OUTPUT WAVEFORMS and Figure 20. Note 16: VVOamp = VVOT -VVOB Note 17: The same rate applies to V-drive signal on VOut pin. Note 18: Informative, not tested on each unit. 6.6 - EW DRIVE SECTION VCC = 12V, Tamb =25°C Symbol Parameter Test Conditions Value Units Min. Typ. Max.
