Original question:
Hi,
I have a few questions about the charge pump behavior vs Vvm supply voltage:
1. What is the expected max Ivcp current when Vvm is 24V? Is this linearly correlated? Will it max out at 25mA?
2. When Vvm is 24V, what is the the VCP operating voltage with respect to VM? Will this remain at 11V?
-Kelvin
Kelvin,
Thanks for posting on the MD forum!
The specs for the charge pump at any VM higher than 13V will match the VM = 13V line in the datasheet.
If you are calculating for external FET needs, section 9.2.1.2.1 External MOSFET Support in the datasheet will be helpful.
Regards,
