MSP430F2272-Q1: MSP430F2272: VBATT Monitor

Hi,

I'm trying to monitor Vbatt using a voltage divider going into an ADC input pin of MSP430F2272. Normal Vbatt thresholds is between 9-16V, so a voltage divider of say 5kohm to Vbatt and 1kohm to GND will see ADC input read 3.2V when Vbatt is 16V and 1.8V when Vbatt is 9V.

My concern is that since absolute maximum voltage rating of the MSP430 pins is at the most 4.4V, any Vbatt transients that produces a higher voltage than 4.4V at the ADC input might damage the MSP430 ADC pin. Do you have any recommendations that allows monitoring Vbatt on MSP430 ADC input without worry of damage?

Thanks,

John
