LTC6811HG-1-3#ZZTRPBF

Description

The LTC6811HG-1-3#ZZTRPBF is a multi-cell battery stack monitor designed to measure voltage, current, and temperature in lithium-ion battery packs. This device provides an accurate and reliable solution for monitoring and balancing high-voltage battery systems.

Key Features

  • High-Voltage Battery Monitoring: Measures up to 18 series-connected cells with a common sense point.
  • Voltage Measurement: 16-bit ADC with ±0.25% accuracy over the entire temperature range.
  • Current Measurement: Requires an external current sense resistor.
  • Temperature Measurement: Uses external thermistor (10kΩ NTC type).
  • Iso1850 / SPI Communication: Interfaces with a host microcontroller via an isolated interface.
  • Cell Balancing: Internal cell balancing switches with adjustable timer.
  • Overvoltage and Undervoltage Protection: Alerts the host microcontroller of any faults.
  • Status Register: Reflects cell voltage, current, and temperature measurement status.
