BQ25120F3A  
SLUSDI4A – OCTOBER 2018 – REVISED APRIL 2021  
BQ25120F3A 700-nA Low IQ Highly Integrated Battery Charge Management Solution  
for Wearables and IoT  
1 Features  
2 Applications  
Increases system operation time between charges  
– Configurable 300-mA buck regulator  
(1.8-V default)  
– 700-nA (typical) Iq with buck converter enabled  
(no load)  
– Configurable load switch or 100-mA LDO  
output (LDO by default. VLDO 1.8-V)  
– Up to 300-mA charge current for fast charging.  
I2C programmable up to 200 mA, external  
resistor setting for 200 mA to 300 mA.  
– 0.5% Accurate battery voltage regulation  
(configurable from 3.6 V to 4.65 V in 10-mV  
steps) 4.35-V default  
Smart watches and other wearable devices  
Fitness accessories  
Health monitoring medical accessories  
Rechargeable toys  
3 Description  
The BQ25120F3A is a highly integrated battery  
charge management IC that integrates the most  
common functions for wearable devices: Linear  
charger, regulated output, load switch, manual reset  
with timer, and battery voltage monitor. The integrated  
buck converter is a high efficiency, low IQ switcher  
using DCS-Controlthat extends light load efficiency  
down to 10-µA load currents. The low quiescent  
current during operation and shutdown enables  
maximum battery life. The device supports charge  
currents from 5 mA to 300 mA.  
– Configurable termination current down to  
500 µA  
– Simple voltage based battery monitor  
– Watchdog timer disabled  
– TS WARM fault disabled (no reduction in  
battery regulation voltage)  
Highly integrated solution with small footprint  
– 2.5-mm x 2.5-mm WCSP Package and six  
external components for minimal solution  
– Push-button wake-up and reset with adjustable  
timers
