产品特点 Features
- The HCPL-3120 contains a GaAsP LED while the HCPL-J312 and the HCNW3120 contain an AlGaAs LED. The LED is optically coupled to an integrated circuit with a power output stage.
- These optocouplers are ideally suited for driving power IGBTs
- 2.5 A maximum peak output current
- 2.0 A minimum peak output current
- 25 kV/μs minimum Common Mode Rejection (CMR) at V CM
- = 1500 V
- Data Sheet
- ILED1
- (Discussion applies to HCPL-3120, HCPL-J312, and HCNW3120)
- The HCPL-3120 contains an under voltage lockout (UVLO)
- VOUT1
- Q1 OFF conditions which cause the HCPL-3120 supply voltage
- (equivalent to the fully-charged IGBT gate voltage) to drop
- Q2 ON below a level necessary to keep the IGBT in a low resistance
- Q2 OFF
- VOUT2 state. When the HCPL-3120 output is in the high state and the supply voltage drops below the HCPL-3120 V threshold
