Product details

Smart charger for 2-cell SMBus packs

It handles charge management for a pair of series cells, with an SPI interface for host communication and over-current fault protection.

Supply headroom and protection

The 28V max supply voltage gives enough headroom to charge a 2-cell stack from a typical 19V or 24V input rail. Over-current protection is built in, so an external fuse or current-sense resistor may be simplified on the BOM. The SPI bus lets a host microcontroller set charge parameters and monitor status — useful for systems that log battery health or enforce charge profiles.

The Tape & Reel variant (TR suffix) is the standard production reel; Cut Tape (CT) is also available for prototyping or small runs.

Frequently asked questions

Is LTC1960CG#TRPBF RoHS compliant?

Yes, the LTC1960CG#TRPBF is ROHS3 Compliant, meeting the latest RoHS directive requirements.

How many cells does LTC1960CG#TRPBF support?

The LTC1960CG#TRPBF supports 2 cells in series, designed for Smart Batteries (SMBus) packs.

Can LTC1960CG#TRPBF charge lithium-ion batteries?

The part is specified for Smart Batteries chemistry, which typically includes lithium-ion packs that follow the SMBus protocol. It is not a general-purpose multi-chemistry charger; the charge algorithm is managed through the SMBus interface.

What is the closest functional equivalent to LTC1960CG#TRPBF?

The LTC1759CG#PBF is a close functional peer — also a smart battery charger from Analog Devices, but it uses an I²C interface instead of SPI and supports only 1 cell. The LTC1960CG#TRPBF handles 2 cells and uses SPI, so a firmware and hardware change is needed to swap.
