Key Features
- Monitors up to 9 battery cells simultaneously with adjustable voltage thresholds for flexible BMS configuration in multi-chemistry packs
- 64-pin LQFP (S-PQFP-G64) package with single-function precision analog design for high-accuracy cell voltage measurement
- Daisy-chainable architecture enabling scalable multi-IC battery stack monitoring in electric vehicle and grid storage applications
Applications
The LTC6812ILWE-1#3ZZPBF is designed for battery management systems (BMS) in electric vehicles, hybrid vehicles, and stationary energy storage where accurate per-cell voltage monitoring of up to 9 cells is required. It supports daisy-chain communication for scalable multi-IC stacks, enabling monitoring of high-voltage battery packs with hundreds of cells. The adjustable threshold feature allows designers to configure overvoltage and undervoltage protection limits to match specific lithium-ion or lithium-polymer cell chemistries.

Frequently Asked Questions
How many battery cells can the LTC6812ILWE-1#3ZZPBF monitor simultaneously, and does it support daisy-chain operation?
The LTC6812ILWE-1#3ZZPBF monitors up to 9 battery cells simultaneously per device. It supports daisy-chain communication, allowing multiple ICs to be cascaded to monitor large battery stacks of 100 or more series-connected cells in electric vehicle or grid-scale energy storage systems—without requiring isolated power supplies for each device in the chain.
What does the adjustable threshold feature in the LTC6812ILWE-1#3ZZPBF enable for battery protection?
The adjustable voltage threshold feature in the LTC6812ILWE-1#3ZZPBF allows designers to set customized overvoltage and undervoltage trip points for each cell in the monitored stack. For example, lithium iron phosphate (LFP) cells with a 2.5 V to 3.65 V safe operating range can be protected with different thresholds than NMC cells rated at 3.0 V to 4.2 V, enabling the same IC to support multiple battery chemistries.
Which package does the LTC6812ILWE-1#3ZZPBF use, and how does this affect board layout for high-voltage BMS designs?
The LTC6812ILWE-1#3ZZPBF is housed in a 64-pin LQFP (S-PQFP-G64) plastic package. The LQFP footprint provides fine-pitch leads on all four sides, allowing compact routing of the 9 cell voltage input pins and communication lines. In high-voltage BMS designs, the exposed perimeter leads also simplify the PCB creepage and clearance layout required for isolation between cell groups in battery stacks exceeding 48 V.
