Tiny Size Micro Air Pressure Sensor For Electronic Cigarette
This is a high sensitive very small air pressure sensor. Metal body for a long lasting life and high quality sensor for constant pressure sensing. Controller chip is designed by ASIC, which will not cause the current MCU scheme to crash or the chip can not be reset due to the lower critical voltage. The chip works stably with a constant output voltage of 3.5V to ensure the smoke volume during smoking, and has the function of short circuit protection of heating wire, which can protect the load power. Output cut-off when resistance is less than 1ohm;
Battery protection: When the battery voltage is less than 2.7V, trickle current charging is adopted, when the battery voltage is greater than 2.7V and when the battery voltage is less than 4.2V, high current charging is adopted, and constant voltage charging is performed at 4.2V. The peripheral application circuit of the system is simple and the cost is low.
Specification & Feature
- Diameter :6.0 mm
- Height :2.5 mm
- No. of Connection/point: 3 PIN
- In power saving mode, the static current is small (< 5uA)
- Inside Short Circuit Protection Function (SCP)
- Embedded Under voltage Protection Function (UVLO)
- Inclusive Overheat Protection Function (OTP)
- Wide voltage charging (4.5-6V), excellent charging performance, safe charging process.
- High accuracy of charge voltage detection (less than 1%)
How it works:
Low Static Working Current (<3μA) There are two working modes: normal working mode and power saving mode. The chip will enter power saving mode once after power on and will stay in power saving mode when it is not smoking. Only when the user is smoking, the chip will enter normal working mode. Therefore, the battery can last long time.
Package includes: 1 x Micro Air Pressure Sensor For Electronic Cigarette (6mmx2.5mm) without wire 3pin
