DA9318
DA9318
High Efficiency, 10 A Direct Charger
A team of engineers is ready to answer your questions
Current doubler delivering up to 10 A charging current, with efficiency of up to 98 % and powering up to 44 W
The DA9318 is optimized to handle high charging currents and at the same time ensure the safety of the battery and the system. It operates together with a main charger, which handles the pre-charge and constant voltage charging duties.
The current doubling is achieved with a high-efficiency capacitive divider that provides an output voltage of VIN/2, which allows the use of standard USB Type-CTMcables for charging currents up to 6 A. The peak efficiency of DA9318is 98 %. With maximum 8 A charging current, DA9318L variant can provide 35 W charging power, whereas the DA9318M variant provides 10 A output current and 44 W charging power.
Features
- 8 A output current (DA9318L)
- 10 A output current (DA9318M)
- 98 % efficiency at 3 A
- 5 % current sense accuracy (DA9318L)
- 10 % current sense accuracy (DA9813M)
- Reverse and forward current protection in IDLE mode
- Safe high-voltage direct charging
- Safety timer and watchdog
- 8-bit ADC to measure voltage and current at the input and output, as well as temperature
- Junction temperature monitoring
- I2C compatible 2-wire interface
Benefits
