The BS45F3832, as an atomiser special purpose flash MCU, includes an integrated atomiser control and touch water detection circuits within an 8-pin SOP small package type. This makes it extremely suitable for use in various products/modules where space is limited such as atomisers, humidifiers along with many others.
This new device uses a new method of touch water detection which greatly improves the water shortage detection precision and reduces the need for an external dry reed pipe. The integrated atomiser control module unit within the MCU is used to generate the atomiser frequency tracking and water shortage detection control. The device has powerful drive capability which can directly drive a power MOS transistor with a high operating efficiency. As there are no heating issues, the external MOS transistor heat sink can be omitted, therefore reducing the required number of external components and resulting in reduced manufacturing BOM costs and PCB area size.
This new device has 2K words of Flash Program Memory, 64 bytes of Data Memory, 32 bytes of True EEPROM Memory and a 12-bit A/D Converter. With regard to packaging, the device is supplied in both 8-pin and 10-pin SOP package types.
