Smart Gate Driver Coupler TLP5214 Application Note-综合文档

Overcurrent protection detects abnormal currents in a circuit and prevents them from damaging the

circuit. For overcurrents in IGBTs used in inverter circuits, stopping any overcurrent as fast as possible is

necessary since there is a risk of the powerful load damaging the circuit when the voltage (V

) between

the short circuit capability. It is necessary to stop the overcurrent within the short circuit capability time

must be designed such that the overcurrent is cut off within 10 μs. Also, many electrical products are

required by safety regulations to have features that protect humans from overcurrent conditions.
