Outputs
6.1.1. 10 A High-Side Output Capabilities
These outputs provide 10 A maximum continuous current with a less accurate
current sensing function. The current sensing is used to detect overcurrent and
provide short circuit protection.
The following table provides specifications for the VMM1615's 10 A high-side
outputs:
