Introduction

AI Translation

The MS99x0T series analog front-end (AFE) ICs include two models: MS9920T and MS9930T. The MS9920T supports up to 5 cells in series, while the MS9930T supports up to 10 cells in series. Via I2C, a host controller can use the MS99x0T to implement battery pack management functions, including monitoring (cell voltage, pack current, pack temperature), protection (charge/discharge FET control), and cell balancing. Various battery chemistries such as lithium-ion and LiFePO₄ are supported. The MS99x0T series operates over a temperature range of -40°C to 85°C.
