power supply line, C1 will also be necessary to improve reliability. Its capacity should be larger than 2.2µF. Note 3: If the line between Hall sensor output and Hall sensor input of IC is long, the noise may occur in this line. But it can be eliminated by adding a capacitor C3. when VCC is larger than 20V. Note 5: The package of AH921 is SOT-23-3. If it is packaged in TO-92S-3，please exchange IN- with IN+. Figure 11. Typical Application of AM4953
