Speed and Position Detection
Features:
1. At a supply voltage of 3.6V, the current consumption is 1uA; At 1.7V, the current consumption is only 300nA, which is the lowest Hall power consumption on the market.
2. Anti-static ability exceeds ±5500V, ensuring reliability
Application on gas meter 1
Two Hall ICs are placed, the pulse output from the IC is used for gas volume detection, and achieves the following two functions:
1. Gas count
2. Anti-theft detection
The above structure code wheel rotates once, and the two Halls each output a low pulse. If one is subjected to magnetic attack, the other has a function; If both of them are subjected to magnetic attack, the antimagnetic alarm is performed.
Application on gas meter 2
Two Hall ICs are placed, the pulse output from the IC is used for gas volume detection, and achieves the following two functions:
1. Gas count
2. Anti-theft detection
The Hall that rotates once in the above structure code wheel outputs a low level signal, and the other one performs anti-magnetic action on the side of the counting Hall. Under normal circumstances, only a high level is output; When a low level is output, an anti-magnetic alarm is performed.
