The small package is ideal for space-constrained applications while also saving costs due to reduced board area.
Typical applications include electric vehicles on-board chargers, motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection.
The device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die.
Applied current flowing through this copper conduction path generates...
