DA9318L - High-Voltage Direct Charger

Datasheet Summary

Description

DA9318L/M is a direct charger using a high-efficiency current doubler with integrated Analog to Digital Converter (ADC) for system monitoring.

The device is especially optimized to handle high charging currents and at the same time ensure the safety of the battery and the system.

Features

  • an 8-bit ADC for input and output current and voltage, and junction temperature monitoring which ensures safety during direct charging. For software supervision a programmable watchdog timer, and for battery overload protection a safety timer, are included. An I2C compatible 2-wire interface is provided for the device control. The DA9318L/M is available in a small WLCSP 3.62 mm × 3.78 mm package. Key Features.
  • 8 A output current (DA9318L).
  • 10 A output current (DA9318M).
  • 98 % effi.

DA9318L/M High-Efficiency, 10 A, High-Voltage Direct Charger General Description DA9318L/M is a direct charger using a high-efficiency current doubler with integrated Analog to Digital Converter (ADC) for system monitoring. The device is especially 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 Type-C™ cables for charging currents up to 6 A. The peak efficiency of DA9318L/M is 98 %.
