AIC1811 Datasheet | Analog Intergrations Corporation

FEATURES l n DESCRIPTION The AIC1811 battery protection IC is designed to protect lithium-ion the battery from to damage or degrading lifetime due overcharge, and Less External Reduction in Board Size due to Miniature Package SOT-23-5 ponents. l l Ultra-Low Quiescent Current at 7 µA (V CC =3.5V). Ultra-Low Power-Down Current at 0.4µA (V CC =2.3V). Precision Overcharge Protection Voltage 4.35V ± 50m V for the AIC1811A 4.30V ± 50m V for the AIC1811B 4.25V ± 50m V for the AIC1811C overdischarge, and/or overcurrent for one-cell lithium-ion battery powered systems, such as cellular phones. The ultra-small package and less required external ponents make it ideal to integrate the AIC1811 into the limited space of battery pack. The accurate ±50m V overcharging detection l l Built-in Delay Time Circuits for Overcharge, Over-discharge, and Overcurrent Protection. Load Detection Function during Overcharge Mode. Two Detection Levels for Overcurrent Protection. 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. l l n APPLICATIONS l Protection IC for One-Cell Lithium-Ion Battery Pack. n TYPICAL APPLICATION CIRCUIT BATT+ FUSE R1 BATTERY 100 C1 0.1 µF 2 3 GND OD OC 1 R3 AIC1811 10M BATTM2 SI9926 5 VCC CS R2 51K M1 SI9926 Protection Circuit for One-Cell Lithium-Ion Battery DS-1811-00 June 7, 00 .analog..tw AIC1811 n ORDERING INFORMATION AIC1811 XCX PACKAGE TYPE V: SOT-23-5 OVERCHARGE PROTECTION A: 4.35V B: 4.30V C: 4.25V ORDER NUMBER AIC1811ACV AIC1811BCV AIC1811CCV (SOT-23-5) PIN CONFIGURATION TOP VIEW VCC 5 CS 4 1 OC 2 GND 3 OD n ABSOLUTE MAXIMUM RATINGS Supply Voltage … … … … … 18V 18V … … … … … … -40°C~85° C -...
