and external capacitor CCTIMR (C6) connected to CTIMR (pin 1). 8. PWM Dimming Control The shutdown delay time is approximated by the following equation: OZ964 provides a low frequency PWM (LPWM) dimming function to perform a wide dimming range of 0% to 100%. The LPWM frequ...
The ignition (turn-on) time is determined by capacitor C9 connected to LCT (pin 6) and is approximated by the following equation: T[second] = CLCT[nF]*0.33 The striking frequency is approximated by the following equation: 3770/ RCT [k?] + 15 fstriking[kHz] = 4*CCT[pF] x 1000 7....
This enables high-accuracy current sense with the use of small current sense resistors (e.g. ≤1 mΩ) to reduce power dissipation and heat. OZ3717 uses one dedicated fast comparator for DOC2 detection and a second dedicated fast comparator for SC detection. Any DOC2/SC fault quickly ...
