10 Power Supply Recommendations
The DRV5032 device is powered from 1.65-V to 5.5-V DC power supplies. A decoupling capacitor close to the
device must be used to provide local energy with minimal inductance. TI recommends using a ceramic capacitor
with a value of at least 0.1 µF.
11 Layout
11.1 Layout Guidelines
Magnetic fields generally pass through most nonferromagnetic materials with no significant disturbance.
Embedding Hall effect sensors within plastic or aluminum enclosures and sensing magnets on the outside is
common practice. Magnetic fields also easily pass through most printed-circuit boards, which makes placing the
magnet on the opposite side possible.
