OZ9313 - O2Micro

OZ9313 High-High Accuracy Battery (Gas) Gauge

OZ9313 is a highly accurate battery (gas) gauge designed to work with high power Battery Management Units (BMUs), specifically O2Micro’s industry leading OZ890, OZ8920, OZ8930 and OZ8940. OZ9313 directly measures charge current and discharge current with an integrated high-accuracy and low-power sigma-delta ADC. Furthermore, OZ9313 is programmed to constantl.
