RFQ (Request for Quotations)It is recommended to request for quotations to get the latest
prices and inventories about the part.
Our sales will reply to
your request by email within 24 hours.
1. You'll receive an order information email in your inbox.
(Please remember to check the spam folder if you didn't hear from us).
2. Since inventories and prices may fluctuate to some
extent, the sales manager is going to reconfirm the order and let you know if there
are any updates.
Shipping starts at $40, but some countries will exceed $40. For
example (South Africa, Brazil, India, Pakistan, Israel, etc.)
The
basic freight (for package ≤0.5kg or corresponding volume) depends on the time zone and
country.
Currently, our products are shipped through DHL, FedEx, SF, and UPS.
Delivery TimeOnce the goods are shipped, estimated delivery time depends on the shipping methods you chose:

The BQ24040DSQR gadget is a highly integrated Li-Ion and Li-Pol linear charger designed for portable applications with minimal space. The gadgets can be powered by an AC adaptor or a USB port. Low-cost unregulated adapters are supported by the high input voltage range with input overvoltage protection.
The battery is charged by a single power output of the BQ24040DSQR. As long as the average system load does not prevent the battery from charging fully during the 10-hour safety timer, a system load may be connected in parallel with the battery.
Conditioning, constant current, and constant voltage are the three phases of the battery charge. An internal control loop tracks the temperature of the IC junction throughout all charge phases and lowers the charge current if an internal temperature threshold is reached.
The charge current detection and charger power stage operations are completely integrated. The charger function includes charge termination, charge status display, and high accuracy current and voltage regulating loops. On the BQ24040DSQR, an external resistor is used to program the pre-charge current and termination current threshold. An external resistor can be used to program the quick charge current value.
