hmc-alh476

Hello. I'm a system designer

 

When I use HMC-ALH476, It's supplied VDD(+4V), and VGG(-0.3V).

 

It's supposed to hold same VGG as -0.3V, but when I measured VGG voltage, it was -0.48V...

 

VGG voltage was dropped -0.3V to -0.48V by HMC-ALH476..

 

That chip's supply current is typical 90mA on datasheet. But chip consumed almost 130mA...

 

I have noidea about it. Is this test condition okay?

 

If anyone know this circumstance, plz let me know....

 

Thank you!
