DRV5055EVM
1 Overview
The DRV5055 family of linear Hall effect sensors sense magnetic fields ranging from 21 mT to 176 mT,
depending on device and supply voltage. For each device, four gains are available. For the DRV5055, the
gains at 3.3 V V
CC
include: 7.5 mV/mT, 15 mV/mT, 30 mV/mT, and 60 mV/mT. These devices operate
from a single 3-V to 5.5-V power supply, drawing a maximum of 10 mA of supply current. These devices
are currently available in a 3-pin SOT-23 or 3-pin TO-92 package.
Table 1 lists available gain options.
