1 Features • High-efficiency, 1.5-MHz, synchronous switchmode buck charger – 92% charge efficiency at 2-A from 5-V input – Optimized for USB voltage input (5 V) • Supports USB On-The-Go (OTG) – Boost converter with up to 1.2-A output – 92% boost efficiency at 1-A output – Accurate constant current (CC) limit – Soft-start up to 500-μF capacitive load – Output short circuit protection • Single input to support USB input and high voltage adapters – Support 3.9-V to 13.5-V input voltage range with 22-V absolute maximum input voltage rating – Maximum power tracking by input voltage limit up to 4.6 V (VINDPM) – VINDPM threshold automatically tracks battery voltage – Auto detect USB SDP, DCP and non-standard adaptors • High battery discharge efficiency with 19.5-mΩ battery discharge MOSFET • Narrow VDC (NVDC) power path management – Instant-on works with no battery or deeply discharged battery – Ideal diode operation in battery supplement mode • High integration includes all MOSFETs, current sensing and loop compensation • 58-μA low battery leakage current with system voltage standby • High accuracy – ±0.5% charge voltage regulation – ±6% at 1.2-A and 1.8-A charge current regulation – ±5% at 0.5-A, 1.2-A and 1.8-A input current regulation • Safety-Related Certification: – IEC 62368-1 CB Certification 2 Applications • EPOS, Portable speakers • Mobile phone accessory • Medical equipment 3 Description The BQ25606 is a highly-integrated standalone 3.0- A switch-mode battery charge management and system power path management device for single cell Li-ion and Li-polymer batteries. The solution is highly integrated with input reverse-blocking FET (RBFET, Q1), high-side switching FET (HSFET, Q2), low-side switching FET (LSFET, Q3), and battery FET (BATFET, Q4) between system and battery. The low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time, and extends battery life during discharging phase.
