1 / 11 page AIC1783 Battery Charge Controller Analog Integrations Corporation 4F, 9, Industry E. 9th Rd, Science Based Industrial Park, Hsinchu Taiwan, ROC www.analog.com.tw DS-1783-00 May 28, 01 TEL: 886-3-5772500 FAX: 886-3-5772510 1 n FEATURES l Fast Charge Control of NiMH/NiCd Batteries. l Fast Charge Termination by: ?V − , ?V 0 , Safety Timer, Maximum Voltage. l Protection against Battery Voltage Fault. l Pulsed Trickle Charge Mode. l Quick and Easy Testing for Production. l 8-pin DIP or SO Packages. n APPLICATIONS Battery Fast Chargers for: l Mobile Phones. l Notebook and Laptop Personal Computers. l Portable Power Tools and Toys. l Portable Communication Equipment. l Portable Video & Stereo Equipment. n DESCRIPTION The AIC1783 fast charge controller IC is designed for intelligent charging of NiMH or NiCd batteries without the risk of overcharge. ?V − detection (-0.25%) and ?V 0 detection (peak voltage timer) are the primary methods employed by the AIC1783 to terminate fast charge. The fast charge can also be cut off by maximum battery voltage along with the safety timer to prevent charging under fault conditions of the charging system or the battery itself. The safety timer period is adjustable for flexible usage that AIC1783 could be applied in the wide range of battery capacity. Test mode is provided for charger manufactures to dramatically reduce production test time. n TYPICAL APPLICATION CIRCUIT REF 1 TIMER 2 MODE 3 GND 4 LED 5 ICON 6 VBT 7 VCC 8 U2 AIC1783 C4 0.1 µF C1 1 µF C3 0.1 µF C7 1000P C10 47nF R10 0.3/5W DC 1 DE 2 CF 3 GND 4 FB 5 VCC 6 IS 7 BOOST 8 U3 AIC1563 + C8 220 µF R9 390K L1 220 µH R1 1K D2 1N5822 D1 1N5822 + C2 220 µF BAT1 + C5 1 µF + C6 10 µF R3 100K R4 120K Q1 2N222 R5 120K + C9 4.7 µF D4 IN4148 D3 1N4148 R13 120/0.5W R2 240K R11 100K VIN R6 680 R7 47K R8 10K VIN 1 VOUT 3 2 GND U1 7805 LED1 RED R12 150K Battery Charge Circuit with Wide Input Voltage Range |
