Over-Discharge Protection
Short Circuit Current Limiting
Battery Open-Circuit Center Tap Protection
Cell Voltage Balancing
Undervoltage Lockout
DESCRIPTION
The Si9730 monitors the charging and discharging of dual-cell
lithium-ion battery packs ensuring that battery capacity is fully
utilized while ensuring safe operation. The Si9730 provides
protection against overcharge, over-discharge, and short
circuit conditions which are hazardous to the battery and the
environment.
Battery voltages of each individual cell are monitored at the
center-tap connection by an internal A/D converter through
the V
C
pin. If one or both of the cells is determined to be
overcharged, an internal cell balancing network “bleeds” off
current at 15 μA until both cells are charged to the same
maximum level. Depending on the condition of each cell, the
Si9730 will switch two external source-connected n-channel
MOSFETs on or off to allow the cells to be charged or to
provide current to the load.
The Si9730 is available in an 8-pin SOIC package with an
operating temperature range of -25 to 85
°
C.
