Low-side switches

Switches designed for driving loads from the low side

parametric-filterView all products
A low-side switch is a simple, cost-effective way to drive stepper motors, relays, solenoids, actuators and other inductive loads from the low side. Our portfolio comprises Darlington transistor and NMOS arrays, which can range from single-channel  to eight-channel devices with voltage support up to 50 V.

Reference design
Smart brake control and diagnostics reference design for servo drives and robotics
This reference design implements safe brake control functionality in servo drives as per IEC EN 61800-5-2 by providing two channel output signals to control an external holding brake. The holding brake will be latched when the power supply is cut off and released when voltage is applied to the (...)
