HT7Q1521 Description
The HT7Q1521 is a high voltage analog-front-end IC for 3 to 8 cell Li-ion rechargeable battery protection. It consists of an accumulative cell voltage monitor and a high accuracy voltage regulator. The device is designed to monitor an accumulative voltage from 1 to N and outputs the divide-by-N voltage to the analog multiplexer with a ±0.5% divided ratio accuracy.
