一,产品概述(General Description) ![]() The jtm6202C is a complete battery charger controller for one (4.22V) cell lithium-ion battery. The jtm6202C provides a small, simple and efficient solution to fast charge Li-ion battery. An external sense resistor sets the charge current with high accuracy. An internal resistor divider and precision reference set the final float voltage to 4.22V per cell with ±1% accuracy.
When the input supply is removed, the jtm6202C automatically enters a low current sleep mode, dropping the battery The jtm6202C is available in the SOP8/PP package. 二.产品特点(Features)![]() Ø Input Supply Range: 4.7V ~ 6V Ø Maximum Charge Current: 1.8A Ø High Efficiency Current Mode PWM Controller Ø End - Charge - Current Detection Output Ø Constant Switching Frequency for Minimum Noise Ø ±1% Charge Voltage Accuracy Ø Automatic Battery Recharge Ø Automatic Shutdown When Input Supply is Removed Ø Automatic Trickle Charging of Low Voltage Batteries Ø Battery Temperature Sensing Ø Stable with Ceramic Output Capacitor Ø SOP8/PP Package 三,应用范围 (Applications)![]() Ø Charging Docks Ø Handheld Instruments Ø Portable Computers 四.技术规格书下载(产品PDF)![]()
