Overview
CS213A Protection IC for 1-Cell Battery Pack Features  Detection Accuracy  Over-charge Detection: 40mV  Over-discharge Detection: 100mV  Discharge Over-current Detection: 20mV  High Withstand Voltage  Absolute maximum ratings: 24V (V- pin and CO pin)  Ultra Small Package  SOT-23-6 Description The CS213A is the 1-cell protection IC for lithium-ion/lithium-polymer rechargeable battery pack.
This protection IC was developed for use with lithium-ion/lithium polymer 1-cell serial batteries.
It detects over-charge, over-discharge, discharge over-current and other abnormalities, and functions to protect the battery by turning off the external FETs.
The IC also has a built-in timer circuit (for detection delay times), so fewer external parts can be used in protection circuit configuration.
The tiny package is especially suitable for compact portable device, i.
e.
slim mobile phone and Bluetooth earphone.
Application  Mobile phone battery packs  Digital camera battery packs  Bluetooth earphone Li-ion battery module Typical Application Circuit EB+ R1 Battery C1 VDD CS213 VSS DO CO FET1 FET2 VR2 EB- Neotec Semiconductor Ltd.
