Silergy SY20812D
The SY20812D is a current-limited P-channel MOSFET power switch designed for USB load-switching or hot plug applications. Its ultra-low RDS(ON) and current limit protect the power source from overcurrent and short-circuit conditions. It incorporates overtemperature protection and reverse blocking functions.| Part No. | SY20812D |
