BOM-fit: supply headroom and charge current ceiling
The LTC4079EDD#TRPBF accepts a maximum supply voltage of 60 V, which covers 48 V telecom rails and 12 V/24 V automotive systems with margin for load-dump transients. The charge current is programmable up to 250 mA — this is the ceiling for the constant-current phase, set by a single resistor to ground. The battery chemistry is multi-chemistry, meaning the IC can charge Li-Ion, Li-Polymer, NiMH, and lead-acid cells without a change in the external component set — the charge algorithm is configured through the PROG pin and timer settings.
Package and thermal: 10-DFN with exposed pad
The part comes in a 10-lead WFDFN with an exposed pad (3 mm × 3 mm). The surface-mount footprint matches the 10-DFN (3x3) supplier device package.
No additional REACH or UL documentation is cited in the standard listing.
