ZHCSJ02A november 2018 – august 2020 DRV5057
PRODUCTION DATA
Magnets generally produce weaker fields as temperature increases. The DRV5057A1 - DRV5057A4 device options have a temperature compensation feature that is designed to directly compensate the average drift of neodymium (NdFeB) magnets and partially compensate ferrite magnets. The residual induction (Br) of a magnet typically reduces by 0.12%/°C for NdFeB, and 0.20%/°C for ferrite. When the operating temperature of a system is reduced, temperature drift errors are also reduced. The DRV5057Z1 - DRV5057Z4 devices options do not compensate for the drift external magnets
