(1) d1 requires approximately the same voltage of power modules. (2) if reverse recovery time of d1 is long, pin1 is applied high voltage. in that case, counterplan for protection which insert a zener diode between pin 1 and 6 is necessary like above diagram. (3) in case pin 2 is operating, the ctrip is expected to be wired as close as possible fr om pin 2 and pin 4. (less than 5cm coming and going) application example of single power supply v cc = 24v dz2 : 8.2v , 1/2w r : 2.7k ~3.3kohm operation of protection circuit application circuit example operation flow on dete cting shortcircuit (1) in case the gate voltage is ?h? and the collector voltage is high, this hybrid ic will recognize the circuit as short circuit and immediately reduce the gate voltage. besides, put out an error signal (?l?) which inform that protection circuit is operating at the same time from pin8. (2) the protection circuit reset and resort to ordinary condition if input signal is ?off? when the premised 1~2msec passed. ( ?off? period needs 10us or more ) (3) when the output rises, t he controlled time detect short circuit (typ 2.6us) is set up so that on-time of igbt can be secured properly. it is possible to adjust that ti me by connecting the capacitor (ctrip) between pin2 and 4. vla541 14 13 1 2 5 4 6 vcc vee rg d1 4.7k vin (5v) ctrip 47uf 47uf dz1 hc04 etc. 30v 8 input signal is off clear alarm enable output yes no start detection of short circuit gate shutdown timer start output alarm end of timer 1 ~ 2ms yes no (*) output voltage with protecti on circuit operating is about -lveel+2v tentative vla541 14 13 1 2 5 4 6 vcc rg d1 4.7k vin (5v) ctrip 47uf 47uf dz1 30v 8 dz2 r
