Subject: [RFC PATCH 5/7] dt-bindings: regulator: bd9576 add FET ON-resistance for OCW
Date: Thu, 11 Feb 2021 14:35:41 +0200 [thread overview]
Message-ID: <b7025d14fc8eb0eac95437ac62e74f64a7cf2b4c.1613042245.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1613042245.git.matti.vaittinen@fi.rohmeurope.com>
BD9576MUF provides over-current protection and detection. Current is
measured as voltage loss over external FET. Allow specifying FET's on
resistance so current monitoring limits can be converted to voltages.
