Product Overview

The BQ25070DQCT is a highly integrated LiFePO4 linear Battery Charger targeted at space-limited portable applications. It operates from either an USB port or AC Adapter and charges a single-cell LiFePO4 battery with up to 1A of charge current. The 30V input voltage range with input over-voltage protections supports low-cost unregulated adapters. It has a single power output that charges the battery and powers the system. The charge current is programmable up to 1A using the CTRL input. Additionally, a 4.9V ±10% 50mA LDO is integrated into the IC for supplying low power external circuitry. The LiFePO4 charging algorithm removes the constant voltage mode control usually present in Li-ion battery charge cycles. Instead, the battery is fast charged to the overcharge voltage and then allowed to relax to a lower float charge voltage threshold. The removal of the constant voltage control reduces charge time significantly.
  • Single cell LiFePO4 charging algorithm
  • Programmable charge current through single input interface
  • 7% Charge current regulation accuracy
  • Thermal regulation and protection
  • Soft-start feature to reduce inrush current
  • Battery NTC monitoring
  • Charging status indication
  • Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
