Using our high-voltage, hermetically sealed microbattery design, we demonstrate microbattery operation while driving devices, including motors and actuators, under ambient condition as a primary power source in single- (∼4 V), double- (∼8 V), and triple-stacked (∼12 V) configurations.
Fig. 14 illustrates a summary of the power consumption of the battery management chip. 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.
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. 1. Wuthibenjaphonchai, N., Haruta, M., Sasagawa, K., et al. (2021).
The proposed battery management chip had smaller charging current and quiescent current than the charging ICs. In Ref. [ 23 ], it integrated two NMOS and used the integrated NMOS as the current sampling resistor. Therefore, the values of charging and discharging overcurrent will change with the battery voltage.
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.
In summary, a new switch method for a one-cell lithium battery management chip was demonstrated in this study. 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.
