UCD90910: Questions for UCD90910

Part Number: UCD90910
Other Parts Discussed in Thread: UCD90124, UCD90120, UCD90124A, UCD90120A
Hi,
Please see questions regarding UCD90910 below:
1) UCD90120 and UCD90124 got the exact same footprint as UCD90910 which can serve as direct drop-in replacement for the UCD90910 right?
2) FPWM1 to FPWM8 from UCD90910 can also be configured as GPIOs right?
3) Even though the data sheet feature the UCD90910 can monitor and sequence 10 voltage rails, but the device can actually monitor and sequence up to 13 power rails right if the PWM pin is used as GPIO?
Thanks.

    Hi

    1.UCD90120/124/910 are different products with the same footprint.  we do not recommend UCD90120/UCD90124 since these are no support on these two device. I would recommend UCD90120A/UCD90124A.  they are drop in solution but it is up to what kind of features of UCD90910 have been used. you may and may not get the same functions

    2. FPWM1-FPMW8 can be used as GPIOs for UCD90120A/124A/90910

    3. No, UCD90910 can only monitor up p 10 rails with 13 monitor pins, the extra 3 pin must be configured as either current or temperature sensing. 

    Regards

    Yihe
