Product details

It accepts a supply voltage up to 28V, making it suitable for industrial and automotive battery management systems where the input rail can vary widely.

Multi-chemistry charging: one BOM for multiple battery types

Because the LTC4012IUF#PBF supports multi-chemistry charging, a single board can handle Li-Ion, LiFePO4, NiMH, or lead-acid packs by changing the charge termination algorithm in the external controller. That saves a board spin when a customer switches battery chemistries mid-production. The constant programmable current lets you set the charge rate with a single resistor — no firmware dependency for the current limit.

The 20-QFN package with exposed pad helps pull heat into the PCB copper plane — make sure the thermal vias are sized for the charge current you plan to run.

Frequently asked questions

What are the equivalent parts for LTC4012IUF#PBF?

The LTC4012IUF-2#PBF is a pin-compatible alternative with the same package, cell count, and temperature range, but its supply maximum is 16.8V instead of 28V. The LTC4012CUF-2#PBF is the commercial-temperature (0°C to 85°C) variant of the -2 version. The LTC4008EGN#PBF is a multi-chemistry charger with a 28V supply but a narrower -40°C to 85°C range and a different package.

How many cells can LTC4012IUF#PBF charge?

It charges 1 to 4 series cells.

Is LTC4012IUF#PBF compatible with LiFePO4 batteries?

Yes, because it supports multi-chemistry charging, it can charge LiFePO4 packs provided the external charge-termination algorithm is configured for the LiFePO4 voltage profile.
