Today, according to the official news of BYD Semiconductor, in response to the double high demand for battery protection chips in terms of precision and power consumption of smart phone batteries, BYD Semiconductor independently developed and launched BM114 series products for smart phones and tablet computers. At present, the product has passed the test certification of many brand end customers and has been shipped in batches.
In view of the current characteristics of lithium battery materials, battery overcharging will have the safety hazard of battery explosion, and deep discharge will shorten the service life of the battery, so high-quality lithium battery protection chips are particularly important for smart phones.

It is reported that one of the biggest highlights of BYD Semiconductor's BM114 series products is that it has an overcurrent detection terminal, which can greatly reduce the impact of temperature changes by using precision resistance detection with external low resistance value, and achieve high-precision overcurrent detection, which currently meets the ±1mV, which is higher than the industry requirements.

It is worth mentioning that the product adopts DFN1.6*1.9-6L package, which can completely replace the international mainstream brand with pin-pin.
BYD Semiconductor battery protection chips were mass-produced and shipped in 2005, and are mainly used in mobile phones, notebooks, smart watches, bracelets, TWS headphones, as well as batteries such as sweepers, vacuum cleaners, electric bicycles, and power tools.
It is understood that the lithium battery protection chip built into the mobile phone battery can effectively monitor and protect the battery overcharge, overdischarge, discharge overcurrent and other conditions.
