CXMD2231 CXMD2232 CXMD2233 is a special IC for electronic cigarettes, using ASIC design. The current MCU program’s crash phenomenon will not happen to it, and the chip can reset when the voltage is lower than the critical voltage. The chip’s working condition is stable, and its constant output voltage is 3.6V, which ensu res the amount of smoke when sm o k i n g. It al s o c o nt a i n s he at i n g wi r e s short-circuit protection function. When the output load is less than 1.4Ω (± 0.5Ω) or less, it is sm o k e l e s s . L o w p o w e r c o n s u m pt i o n i n power-saving mode is less than 3uA. Meanwhile, the chip has a visual LED work indication function. Depending on the application status, there will be distinguishable LED indications in the process of smoking, voltage detection, sho rt ci rcuit protection and cha rging. The chip’s battery protection function is perfect, which means its charging performance is excellent and charging process is safety. It also has charge control circuit in it, and can support common adapters and USB charging devices, etc. When the charging voltage is less than 2.7V to trickle charge, the chip can ensure safety and not to damage the battery. When charged to more than 2.7V, high current charging starts and when the voltage is close to 4.2V, charging current is gradually declined. The charging voltage detection error can be less than 1%. The external application circuit of system is simple. The integrated power tube in this IC is convenient to process and power consumption is extremely low. Using SOT-23-5 package, the size is small. There are very few external components: only one LED light and a capacitor, so the system c o s t i s l o w
