ACPL-32JT-500E

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18
During a Short Circuit:
1. DESAT terminal monitors IGBT’s V
CE
voltage.
2. When the voltage on the DESAT terminal exceeds 7 V, the IGBT gate voltage (V
GATE
) is slowly lowered by soft shutdown
pin SSD. Output driver V
o
enters into high impedance state.
3. Output driver V
o
ignores all PWM commands during mute time t
DESAT(MUTE)
.
4. FAULT output goes Low, notifying the microcontroller of the fault condition.
5. Microcontroller takes appropriate action.
6. When t
DESAT(MUTE)
expires, the LED input needs to be kept Low for t
DESAT(RESET)
before fault condition can be cleared.
FAULT status will return to High.
7. Output starts to respond to LED input after fault condition is cleared.

Notes:
1. Isolation characteristics are guaranteed only within the safety maximum ratings, which must be ensured by protective circuits in the application.
Surface mount classication is Class A in accordance with CECCOO802.
2. Refer to the Optocoupler section of the Isolation and Control Components Designer’s Catalog, under Product Safety Regulation section IEC/EN/
DIN EN 60747-5-5, for a detailed description of Method a and Method b partial discharge test proles.
