LINEAR TECHNOLOGY LTC6801HG#PBF BATTERY MONITOR, MULTICELL, 36SSOP

Обзор продукта

The LTC6801HG#PBF is a multicell Battery Monitoring IC incorporating a 12-bit ADC, a precision voltage reference, sampled comparator and a high voltage input multiplexer. The LTC6801 can monitor as many as 12 series connected battery cells for overvoltage, under voltage and over temperature conditions, indicating whether the cells are within specified parameters. The LTC6801 generates a clock output when no fault conditions exist. Differential clocking provides high noise immunity and ensures that battery stack fault conditions cannot be hidden by frozen bits or short circuit conditions. Each LTC6801 can operate with a battery stack voltage up to 60V and multiple LTC6801 devices can be stacked to monitor each individual cell in a long battery string. When multiple devices are stacked, the status signal of each LTC6801 can be daisy-chained, without opto-couplers or isolators, providing a single status output for the entire battery string.
