Features

Protects and individually monitors two Li-Ion series cells for overvoltage, undervoltage Monitors pack for overcurrent Designed for battery pack integration Minimal external components Drives external FET switches Selectable overvoltage OV ) thresholds

The bq2058T Lithium Ion Pack Supervisor is designed to control the charge and discharge cell voltage limits for two lithium-ion (Li-Ion) series cells, accommodating battery packs containing series/parallel configurations. The low operating current does not overdischarge the cells during periods of storage and does not significantly increase the system discharge load. The bq2058T can be part of a low-cost Li-Ion charge control system within the battery pack. The bq2058T controls two external FETs to limit the charge and discharge potentials. The bq2058T allows charging when each individual cell voltage is below VOV (overvoltage limit). If the voltage on any cell exceeds VOV for a user-configurable delay period (tOVD), the open-drain CHG pin goes to the high-impedance state, shutting off

charge to the battery pack. This safety feature prevents overcharge of any cell within the battery pack. After an overvoltage condition occurs, each cell must fall below VCE (charge enable voltage) for the bq2058T to re-enable charging. The bq2058T protects batteries from overdischarge. If the voltage on any cell falls below VUV (undervoltage limit) for a user-configurable delay period (tUVD), the DSG output is driven low, shutting off the battery discharge. This safety feature prevents overdischarge of any cell within the battery pack. The bq2058T also stops discharge on detection of an overcurrent condition, such as a short circuit. If an overcurrent condition occurs for a userconfigurable delay period (tOCD), the DSG output is driven low, disconnecting the load from the pack. DSG remains low until removal of the short circuit or overcurrent condition.
