Battery monitor for nRF51822

[Bbrotherone]

Hi.

I would like to measure the battery voltage using ADC in MCU. PCB has limited space, I consider to use the IC for this application. 

The following is the LDO with battery monitoring feature.

I wonder If  it is compatible with nRF51822 chip.

Thanks.

Hi,

Could you elaborate what you mean by compatible, is there a specific parameter you are concerned about?

The LDO you have linked can be used with the nRF51822.
If you connect the BM output pin to an analogue input pin on the nRF51822, you can use the ADC to get the battery level measurements.

Best regards,
Karl
