6 FAQs about [Low power consumption lithium battery boost chip]

How much power does a lithium battery management chip consume?

The battery management chip consumes 0.838 μA of quiescent current, and its power down current is less than 10 nA. The two current detection circuits and bandgap circuits consume almost more than half of the power. This is the overhead of a single lithium battery management chip at a power supply of 3.6 V. Fig. 13. Chip microphotograph. Fig. 14.

How does a lithium battery management chip work?

Based on the 0.18 μm 5 V process, the circuit and the switch have been integrated into a single lithium battery management chip. The measurements show that the chip can reliably protect the battery from overvoltage, under voltage and overcurrent with low power consumption.

Can a lithium battery management chip protect the battery from overvoltage?

How to reduce the size of lithium battery management system?

To decrease the size caused by the traditional battery management system and minimize the cost effectively, a new switch and current detection circuits were designed and integrated into the lithium battery management chip. Moreover, the measurements indicate that the proposed circuit is cost-effective and more competitive.

Can a single lithium battery management chip be integrated?

In this study, the current sampling method and the highly integrated switch proposed are successfully integrated into a prototype single lithium battery management chip, which was designed by the authors and fabricated with 0.18 μm 5 V technology. Fig. 13 demonstrates the die microphotograph of the chip. The proposed switch occupies 0.2829 mm 2.

What are the advantages of a low power chip?

The low circuit complexity and small component count means that the chip has a very low quiescent current, which extends the battery life of connected devices. Modulation of high and low-frequencies means that the chip can be tuned to offer high efficiency for low-power systems.
