Key Features

This chip is a single cell battery management chip, which provides battery voltage detection, temperature detection and equalization functions. The temperature detection function of the chip does not need NTC and related peripheral circuits. The chip supports internal equalization without peripheral circuits. The chip has a certain self diagnosis ability, and supports over-voltage and under voltage alarms, high and low temperature alarms, and other chip related abnormal alarms.



Advantage


1) The chip can be directly attached to the flexible PCB (FPCB), simplifying the circuit and eliminating the slave board.

2) The chip has a built-in temperature sensor, which saves materials without NTC and related peripheral circuits.

3) Provide more temperature detection coverage points than traditional NTC schemes.

4) The chip supports asil-d functional safety level.

Single-Cell-Monitoring IC – EIS function(1)

EIS (AC impedance spectroscopy) is the core function of battery management (BMS) chip of Datang NXP semiconductor company, which is different from traditional chip. EIS is closely related to various states of the cell, including cell temperature, cell power, cell aging degree and cell anomaly prediction. As a new function of BMS, EIS is widely used. At the same time, it also makes some high-end applications in this field possible. The industry began to pay extensive attention to this chip and EIS. In this issue, we will explain in detail the application of EIS in BMS system.
