Notes:
1. Reverse connection of power supply may break the device. A countermeasure is needed such as using reverse power protection
diode D1 between power supply and Vdd terminal. In such case of using reverse power protection diode D1 because of there is no
way to return current to power supply, please take necessary measures like below.
- Connect Dz (Zener diode) between Vdd and Vss terminal, not to exceed the absolute maximum rating voltage.
- Connect a capacitor C1 between Vdd and Vss terminal, to make the path of return current to power supply.
The AH5792 has an open-drain tachometer FG output that follows the half (1/2) the magnetic change frequency. A pull-up resistor
(10Kohm, typically for System Power = 5V) connected to a supply voltage.
