TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The DRV5012 device is typically used in rotary applications for brushless DC (BLDC) motor sensors or incremental rotary encoding. To ensure reliable functionality, the magnet should apply a flux density at the sensor greater than the maximum BOP and less than the minimum BRP thresholds. It is good practice to add additional margin to account for mechanical tolerance, temperature effects, and magnet variation. 8.2 Typical Applications 8.2.1 BLDC Motor Sensors Application Figure 13. BLDC Motor System 8.2.1.1 Design Requirements For this design example, use the parameters listed in Table 1. Table 1. Design Parameters DESIGN PARAMETER EXAMPLE VALUE Number of motor phases 3 Motor RPM 3000 Number of magnet poles on the rotor 6 Magnetic material Bonded Neodymium Peak magnetic flux density at the Hall sensors ±15 mT Battery voltage range (VBAT) 2 to 3.5 V |
