Thermal derating curve, dependence of safety limiting value with casefig temperature per IEC/ HCPL-4562 17b EN/DIN EN 60747-5-2 Conversion from HCPL4562 to HCNW4562 In order to obtain similar circuit performance when converting from the HCPL-4562 to the HCNW4562, it is recommended to increase the Quiescent Input Current, IFQ, from 6 mA to 10 mA. If the application circuit in Figure 4 is used, then potentiometer R4 should be adjusted appropriately. Design Considerations of the Application Circuit The appIication circuit in Figure 4 incorporates several features that help maximize the bandwidth performance of the HCPL-4562/HCNW4562. Most important of these features is peaked response of the detector circuit that helps extend the frequency range over which the voltage gain is relatively constant. The number of gain stages, the overall circuit topology, and the choice of DC bias points are all consequences of the desire to maximize bandwidth performance. To use the circuit, first select R1 to set VE for the desired LED quiescent current by: IFQ = VE G V VE R 10 R4 ( I PB / I F ) R 7 R 9 ( 1) For a constant value V INp-p , the circuit topology VIN /R 4 ( 2) i F p-p p-p (adjusting gainV with R4) preserves linearity by VE the G V E R 10 IiF Q = the modulation ( 1) keeping factor (MF) dependent only F p-p p-p p-p R i PB p-p ( I=PB /VINp-p I Fp-p ) R 7R 9 ( 3) on VE. 4 I F Q V I PB Q G VVE R V E 10 Ii F Q = VE /R (( 1) 2) F p-p R 4IN 4( I PB / I F ) R 7 R 9 p-p i F (( p-p) V INp-p p-p p-p) VE ) : G R FIactor (( 4) GV V VEE= R 10 i p-p= V( MF E i PB 10 V 1) p-p p-p2 I VVINp-p p-p 2 Ii FFFQQp-p = R 1) F Q E = ((( 3) ( I / I ) R R V G V R V /R 2) 4 PB F 7 9 E4INI 4( I PBV/ V EF ) R 107 R 9 FIp-p R I p-p I F QF Q= ( 1) PB Q E R4 ( I PB / I F ) R 7 R 9 i PB VRINp-p p-p p-p p-p p-p 9 p-p V /R 2) iiiFFp-p IN 4 i -= 3) VBINp-p p-p V = V - V [V (((5) V /R 2) F ( p-p) OF p-p CC B E E p-p X - ( I PB Q - I B XQ ) R 7 ] IN 4 ( p-p) Modulation p-p 4 I I V R FQ PB Q Fiactor ( MF ) : ( 4) 10E= V /R ( 2) F p-p IN 4 2 I p-p 2 V i PB p-p VINp-p ii F p-p FQ E p-p p-p p-p F p-p p-p = VINp-p p-p p-p i PB p-p (( 3) iI 3) i =p-p)VINp-p V p-p V iIIFFp-p Q PBp-p Q F (( p-p) p-p INp-p p-p VEE= F Q ( PB Q = F actor MFIPB ) :p-p ( 4) 3) VEQR210I F QRV9 E 2 VE I F=Q V G-VI PB VIOPB V - [ V ( I I ) R ] ( 5) ( 6) BE BE X PB Q B XQ 7 Q CC R 10 VINp-p p-p p-p) R 7 R ii94FF (((( p-p) p-p) p-p p-p) = VINp-p FFFor actor ( MF ) : ( a given G , V , and V , DC output voltage will vary actor ( MF ) : V 2 = CC ( 4) 4) i Ep-p) V F QR 9 V2 E 2F (II( p-p) 2INp-p Vp-p F Q E only with h .
