11 / 30 page VCC time 3 V tON Output time 95% × VQ Invalid 11 DRV5055 www.ti.com SBAS640 – JANUARY 2018 Product Folder Links: DRV5055 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated Feature Description (continued) 7.3.5 Operating VCC Ranges The DRV5055 has two recommended operating VCC ranges: 3 V to 3.63 V and 4.5 V to 5.5 V. When VCC is in the middle region between 3.63 V to 4.5 V, the device continues to function, but sensitivity is less known because there is a crossover threshold near 4 V that adjusts device characteristics. 7.3.6 Sensitivity Temperature Compensation For Magnets Magnets generally produce weaker fields as temperature increases. The DRV5055 compensates by increasing sensitivity with temperature, as defined by the parameter STC. The sensitivity at TA = 125°C is typically 12% higher than at TA = 25°C. 7.3.7 Power-On Time After the VCC voltage is applied, the DRV5055 requires a short initialization time before the output is set. The parameter tON describes the time from when VCC crosses 3 V until OUT is within 5% of VQ, with 0 mT applied and no load attached to OUT. Figure 11 shows this timing diagram.
