INA241A: Is there 2 channels current sensing like INA241?

Eason Tian

Part Number: INA241A

Tool/software:

Hi Expert,

my customer wants to use INA241 x 2 in motor drive phase current sensing, is there one chip solution for 2 channels INA241?

Or other small size solution to replace INA241x2

Thanks

Hello Eason,

We have multi channel devices but not with the same capabilities as the INA241 with the PWM rejection. There is an integrated shunt version (INA790) but the current range needs to be correct to use that device and the shunt size needs to be accounted for when comparing. The INA241 is one of the smallest single packages in the SOT-23.

Here are our dual channels but I do not think they will meet requrirements: https://www.ti.com/product-category/amplifiers/current-sense/products.html#2192=Dual%20Channel&
