The TS12001-C021DFNR is a two-cell linear Li-Ion battery management IC (BMS IC). It can monitor and protect a two-cell series Li-ion battery pack against overcharge, over-discharge, and overcurrent conditions. It is designed to provide a cost-effective solution for two-cell battery packs in a variety of applications.

The TS12001-C021DFNR is placed between the battery pack and the charger. It continuously monitors the voltage on both cells and compares it with the programmed threshold voltages. If one of the cells falls below the discharge threshold, the output of the IC is disabled, protecting the battery from over-discharge. If the voltage on one of the cells rises higher than the overcharge threshold, the output of the IC is disabled, protecting the battery from overcharge.

The IC also has an overcurrent-protection circuit that protects the batteries from overcurrent draw. The current sensing circuit senses the current level and compares it to a programmed threshold. If the current draw exceeds the pre-programmed value, the output is disabled, protecting the batteries from overcurrent draw.

The TS12001-C021DFNR is a cost-effective solution for two-cell battery packs and is suitable for applications such as consumer electronics, wearables, and medical devices. It is available in a 2x2mm overcharge/over-discharge/overcurrent-protection package, making it ideal for space-constrained applications.

The working principle of the TS12001-C021DFNR is quite simple. The integrated circuits monitor the voltage on two cells and continuously compare it with the pre-programmed threshold values. If the voltage on either cell exceeds the threshold value, the output of the IC is disabled, protecting the battery from overcharge or over-discharge.

The current sensing circuit senses the current level and compares it to a pre-programmed threshold value. If the current draw exceeds the pre-programmed value, the output of the IC is disabled, protecting the battery from overcurrent draw.The TS12001-C021DFNR is a low-cost, space-saving solution for two-cell battery management applications and is suitable for consumer electronics, wearables, and medical devices.
