8.4 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.

8.5 Layout

8.5.1 Layout Guidelines

Magnetic fields pass through most nonferromagnetic materials with no significant disturbance. It is common

practice to embed Hall effect sensors within plastic or aluminum enclosures and sensing magnets on the

outside. Magnetic fields also easily pass through most printed-circuit boards, which makes placing the magnet

on the opposite side possible.
