34V input, 18V pack — charger for industrial and automotive battery stacks
It accepts a supply input up to 34V, which gives headroom for 24V industrial rails or automotive systems with load-dump transients. The charge current is programmable up to 2A, and a timer termination option is built in — no external microcontroller needed for basic charge management.
Charge profile and chemistry flexibility
Multi-chemistry support means this IC can handle Li-Ion, LiFePO4, or lead-acid chemistries with appropriate resistor divider settings on the output voltage feedback. The constant-current, constant-voltage (CC/CV) profile is standard for Li-Ion; the programmable timer provides a safety backup if the termination current threshold is not reached. The 2A maximum charge current suits 4S or 5S packs.
The package with exposed pad (3.00 mm width) is a surface-mount design.
Lifecycle — active, no LTB watch needed
There is no last-time-buy window, no NRND flag, and no announced end-of-life. The ROHS3 compliance is confirmed.
