TXB0108: drive relay

Dear teams,

I used TXB0108 drive relay,the circuit diagram is as follows：

I cannot drive the relay in actual use, and I feel that the driving ability is insufficient.

I was able to drive relays with LSF0108 before. Could you please help me see what the reason is?

Alice：

您好， 已经收到了您的案例，调查需要些时间，感谢您的耐心等待。

您好，LSF0108是没有低电平灌电流的能力的，不能直接用于驱动继电器，请使用继电器驱动芯片。
