SHIKUES Low Power Consumption, High Precision, HighESD

1-Cell Li-ion and Li-Polymer

Battery Voltage and Current Protection IC

‧SHIKUES battery protection ICs are featured for accurately monitoring Li-ionor Li-Polymer

battery voltage and current when charging and discharging the batteries. When over charge, over

discharge and short circuit conditions happened, SHIKUES battery protection ICs will control the

charging or discharging output pins to control charge or discharge MOSFETsto cut off the

charging or discharging path accordingly to protect the batteries frombeing damaged.

‧SHIKUES battery protection ICs monitor the charge/discharge/short circuit current

by external current sensing resistor, to provide very precise current sensing control.

‧SHIKUES battery protection IC embeds with high ESD protection circuit to prevent from

ESD issues in mass production and in use.

‧SHIKUES battery protection IC power consumption when normal operation is low. For

power saving, SHIKUES battery protection IC provides 2 power saving modes : Standby mode

and Power Down mode.
