Characteristic parameters and charging circuit of the power management chip bq24040 Chinese information
The bq24040 series of devices are highly integrated lithium-ion battery linear chargers targeted at space-constrained portable applications. The device operates from either the USB port or the AC adapter. High input voltage range input overvoltage protection supports low-cost unregulated adapters.
The bq24040 has a single output power for battery charging. System Load As long as the average system load does not keep the battery fully charged the 10 hour safety timer can be placed in parallel with the battery.
Characteristic parameters charging
1% charging voltage accuracy
10% charging current accuracy
USB maximum input current limit for pin selection (100mA and 500mA)
Programmable charge cutoff point and precharge current limit
High voltage (3.45V) chemical support via bq24045
Protect
30V input level; 6.6V or 7.1V input overvoltage protection
Input voltage dynamic power management
125 degrees Celsius thermal management; 150 degrees Celsius thermal shutdown protection
