(2) See the Ratiometric Architecture section. (3) BL describes the minimum linear sensing range at 25°C taking into account the maximum VQ and Sensitivity tolerances. (4) See the Sensitivity Linearity section. (5) STC describes the rate the device increases Sensitivity with temperature. For more information, see the Sensitivity Temperature Compensation For Magnets section. 6.6 Magnetic Characteristics for VCC = 3 V to 3.63 V and 4.5 V to 5.5 V, over operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS(1) MIN TYP MAX UNIT VQ Quiescent voltage B = 0 mT, TA = 25°C VCC = 5 V 2.43 2.5 2.57 V VCC = 3.3 V 1.59 1.65 1.71 VQΔT Quiescent voltage temperature drift B = 0 mT, TA = -40°C to 125°C versus 25°C ±1% × VCC V VQRE Quiescent voltage ratiometry error(2) ±0.2% VQΔL Quiescent voltage lifetime drift High-temperature operating stress for 1000 hours <0.5% S Sensitivity VCC = 5 V, TA = 25°C DRV5055A1 95 100 105 mV/mT DRV5055A2 47.5 50 52.5 DRV5055A3 23.8 25 26.2 DRV5055A4 11.9 12.5 13.2 VCC = 3.3 V, TA = 25°C DRV5055A1 57 60 63 DRV5055A2 28.5 30 31.5 DRV5055A3 14.3 15 15.8 DRV5055A4 7.1 7.5 7.9 BL Linear magnetic sensing range(3)(4) VCC = 5 V, TA = 25°C DRV5055A1 ±21 mT DRV5055A2 ±42 DRV5055A3 ±85 DRV5055A4 ±169 VCC = 3.3 V, TA = 25°C DRV5055A1 ±22 DRV5055A2 ±44 DRV5055A3 ±88 DRV5055A4 ±176 VL Linear range of output voltage(4) 0.2 VCC – 0.2 V STC Sensitivity temperature compensation for magnets(5) 0.12 %/°C SLE Sensitivity linearity error(4) VOUT is within VL ±1% SSE Sensitivity symmetry error(4) VOUT is within VL ±1% SRE Sensitivity ratiometry error(2) TA = 25°C, with respect to VCC = 3.3 V or 5 V –2.5% 2.5% SΔL Sensitivity lifetime drift High-temperature operating stress for 1000 hours <0.5% % |
