1. Description

LTC6811HG-1#3ZZTRPBF is a multi-cell battery pack monitor, which has the following characteristics: Can measure up to 12 batteries connected in series The total measurement error is less than 1.2mV. cell The LTC6811 has a measurement range of 0V to 5V Suitable for most battery chemistries. All 12 cells are fine Measured in 290µs, a lower data acquisition rate can Choose a high noise reduction effect. Multiple LTC6811 devices can be connected in series, allowing simultaneous monitoring of long, high-voltage batteries Battery string. Each LTC6811 has an isoSPI interface for High-speed, anti-radio frequency interference, long-distance communication. Using LTC6811-1, multiple devices can be connected to A daisy chain, each host has a host processor connection equipment. Using LTC6811-2, multiple devices are connected in parallel with the host processor, each device Solve individually.

LTC6811 can be powered directly by battery Stacked or isolated from the power supply. LTC6811 includes Passive balance of each unit with independent PWM Duty cycle control of each unit. Other features include Onboard 5V regulator, five general I/O lines and one In sleep mode, the current consumption is reduced to 4µA.
