Description

The LTC6812ILWE-1#3ZZPBF is a Linear/Analog Devices battery-management IC in the LTC6812 family. It is a 12-channel battery monitor designed for series-connected Li‑ion/Li‑ion packs, used in BMS applications. Key ideas:
- Monitors up to 12 individual cell voltages, plus pack current sensing and fault diagnostics.
- Supports active cell balancing via external FETs and a daisy-chained SPI-like interface to a host MCU or other LTC6812 devices, scalable for large packs.
- Provides diagnostic and protection features suitable for automotive, energy storage, and portable power applications.
The suffixes ILWE-1 and #3ZZPBF denote package/variant and manufacturing traceability:
- ILWE-1 indicates a specific package/temperature grade variant of the device.
- #3ZZPBF is the production lot/revision code and Pb-free (lead-free) marking for sourcing and compliance.

Features

Here are the key features of LTC6812ILWE-1 #3ZZPBF (battery monitor/balancer):
- 12-channel cell-voltage monitoring per device for Li-ion stacks; supports larger packs via daisy-chaining multiple LTC6812 devices.
- Passive per-cell balancing with on-chip drives (per-channel balancing capability).
- SPI-like serial interface with daisy-chain capability for multiple devices on a common bus.
- High-accuracy cell voltage measurements with built-in calibration and diagnostic data.
- Fault/diagnostic features: over/under voltage, open/short cell conditions, and other pack-health alarms.
- CRC/data integrity for communications and self-test capabilities.
- Low quiescent current with wake/sleep operation for power efficiency.
- Industrial temperature range and packaging suitable for BMS environments (ILWE variant; RoHS compliant).
Note: For exact electrical specs (voltage range, accuracy, balancing current, timing, and pinout), please refer to the LTC6812 datasheet and the specific package VARIANT documentation.

Package

It uses a 28-pin TSSOP package (Pb-free, RoHS compliant).

Pinout

- Pin count: 28 pins (28-pin package typical for LTC6812 variants).
- Function: 12-channel battery cell monitor for multi-cell packs; measures cell voltages (VC1–VC12) and pack voltage, and communicates to a host MCU via a four-wire SPI-like interface (SCK, SDI, SDO, CS) in a daisy-chain capable configuration.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). It is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits (ADI acquired Linear Technology in 2017).

Application

Application areas: Battery management systems for multi-cell lithium‑ion packs (up to 12 cells in series). Used in automotive and light‑duty EV battery packs, stationary energy‑storage systems (home, commercial, grid‑scale), solar/wind storage, UPS and telecom backup batteries, industrial and robotics power packs, and smart tool batteries. It monitors individual cell voltages, pack current, and temperature to enable safe operation, fault detection, and integration with a BMS controller for protection and balancing.
