Features

General Description

the battery pack. After an overvolt-

age condition occurs, each cell must

fall below V_CE(charge enable voltage)

for the bq2058 to re-enable charging.

➤ Protects and individually moni-

tors three or four Li-Ion series

cells for overvoltage, undervolt-

age

The bq2058 Lithium Ion Pack Super-

visor is designed to control the charge

and discharge cell voltages for three or

four lithium ion (Li-Ion) series cells,

accommodating battery packs contain-

ing series/parallel configurations. The

low operating current does not over-

discharge the cells during periods of

storage and does not significantly in-

crease the system discharge load. The

bq2058 can be part of a low-cost Li-Ion

charge control system within the bat-

tery pack.

The bq2058 protects batteries from

overdischarge. If the voltage on any

cell falls below V_UV(undervoltage

limit) for a user-configurable delay pe-

riod (t_UVD), the DSG output is driven

high, shutting off the battery dis-

charge. This safety feature prevents

overdischarge of any cell within the

battery pack.

➤ Monitors pack for overcurrent

➤ Designed for battery pack inte-

gration

➤ Minimal external components

➤ Drives external FET switches

➤ Selectable overvoltage (V_OV

)

The bq2058 also stops discharge on

detection of an overcurrent condition,

such as a short circuit. If an overcur-

rent condition occurs for a user-

configurable delay period (t_OCD), the

DSG output is driven high, disconnect-

ing the load from the pack. DSG re-

mains high until removal of the short

circuit or overcurrent condition.

thresholds

The bq2058 controls two external FETs

to limit the charge and discharge poten-

tials. The bq2058 allows charging when

each individual cell voltage is below V_OV

(overvoltage limit). If the voltage on any

cell exceeds V_OVfor a user-configurable
