Low power, low drift voltage reference source GX3033 replaces REF3033 for battery formation application

Battery formation is a key process in the production of lithium batteries. Through charging and discharging cycles of the battery cells, active substances are activated, electrochemical performance is stabilized, and qualified cells are selected. This process requires extremely high precision in voltage and current control. Small voltage deviations may lead to insufficient battery capacity, shortened cycle life, and even safety hazards. This article mainly introduces the application of replacing REF3033 with a GX3033 voltage reference source for battery formation. The GX3033 has a maximum initial accuracy of ± 0.15%, which can meet the high-precision formation requirements.

GX3033 is the preferred benchmark source for high-end chemical equipment due to its ultra-high precision and industrial grade reliability. This voltage reference source has a temperature drift of 10ppm/° C, a maximum initial accuracy of ± 0.15%, low operating current, power consumption of less than 125ua, and is compatible with most ADCs and DACs. It offers a small SOT-23 package. The low output voltage lag and low long-term output voltage drift of GX3033 further improve the stability and reliability of the system. In addition, the small size and low operating current (125 μ A) of GX3033 are advantageous for mobile and battery powered applications.

Main functions of GX3033:

• Initial accuracy: ± 0.15% maximum value

• Temperature coefficient: from -40 ° C to+125 ° C, with a maximum value of 35ppm/°

• Operating temperature range: -40 ° C to+125 ° C

• Ultra low voltage: 200mV

• Input voltage: 2.7~5.5V

Long term stability: 45ppm/1000 hours

• Small package: SOIC-23 package pins
