Product details

Battery stack monitoring for BMS boards

The LTC6803IG-4#PBF is a multi-chemistry battery monitor IC from Analog Devices, designed to measure and balance 1 to 12 series-connected cells in a battery management system. It communicates over a serial interface and includes integrated over/under voltage fault protection, making it suitable for lithium-ion, LiFePO4, lead-acid, and other chemistries in automotive, industrial, and energy storage packs.

Surface-mount assembly with a 0.65 mm typical lead pitch. The 44-SSOP is a rework-friendly package — a hot-air station can lift it without pad damage if the board is preheated to 100°C and the flux is active. Pin 1 is clearly marked on the top mold; no orientation ambiguity.

Supplied in tube packaging.

Frequently asked questions

What is the difference between LTC6803IG-4#PBF and LTC6803IG-3#PBF?

Both are functionally identical multi-chemistry battery monitors supporting 1 to 12 cells with a serial interface and over/under voltage protection in the same 44-SSOP package. The -4 and -3 suffixes denote different address or configuration options in the LTC6803 family — the pinout and footprint are the same, so one can replace the other on the same PCB layout if the host firmware accommodates the addressing difference.
