PS9552,PS9552L1,PS9552L2,PS9552L3 2.5 A OUTPUT CURRENT, HIGH CMR IGBT GATE DRIVE PHOTOCOUPLER 8-PIN DIP PHOTOCOUPLER −NEPOC Series−
DESCRIPTION The PS9552, PS9552L1, PS9552L2 and PS9552L3 are optically coupled isolators containing a Ga Al As LED on the input side and a photo diode, a signal processing circuit and a power output transistor on the output side on one chip. The PS9552 Series is designed specifically for high common mode transient immunity (CMR), high output current and high switching speed. The PS9552 Series is suitable for driving IGBTs and MOS FETs. The PS9552 Series is in a plastic DIP (Dual In-line Package). The PS9552L1 is lead bending type for long creepage distance. The PS9552L2 is lead bending type for long creepage distance (Gull-wing) for surface mount. The PS9552L3 is lead bending type (Gull-wing) for surface mounting.
