1 / 8 page AIC1811 One-Cell Lithium-Ion Battery Protection IC DS-1811-00 June 7, 00 www.analog.com.tw 1 n FEATURES l Reduction in Board Size due to Miniature Package SOT-23-5 and Less External Components. l Ultra-Low Quiescent Current at 7 µA (V CC=3.5V). l Ultra-Low Power-Down Current at 0.4 µA (V CC =2.3V). l Precision Overcharge Protection Voltage 4.35V ± 50mV for the AIC1811A 4.30V ± 50mV for the AIC1811B 4.25V ± 50mV for the AIC1811C l Built-in Delay Time Circuits for Overcharge, Over-discharge, and Overcurrent Protection. l Load Detection Function during Overcharge Mode. l Two Detection Levels for Overcurrent Protection. n APPLICATIONS l Protection IC for One-Cell Lithium-Ion Battery Pack. n DESCRIPTION The AIC1811 battery protection IC is designed to protect lithium-ion battery from damage or degrading the lifetime due to overcharge, overdischarge, and/or overcurrent for one-cell lithium-ion battery powered systems, such as cellular phones. The ultra-small package and less required external components make it ideal to integrate the AIC1811 into the limited space of battery pack. The accurate ±50mV overcharging detection voltage ensures safe and full utilization charging. Three different specification values for overcharge protection voltage are provided for various protection requirements. The very low standby current drains little current from the cell while in storage. n TYPICAL APPLICATION CIRCUIT BATT- BATT+ 51K 5 4 3 2 1 R2 R3 FUSE C1 0.1 µF R1 100 10M M2 SI9926 M1 SI9926 OC CS OD GND VCC AIC1811 Protection Circuit for One -Cell Lithium-Ion Battery |
