Overview

Our integrated circuits and reference designs enable you to build a digital output module, enabling low-side and high-side driving capabilities, push-pull high frequency outputs known as pulse train output (PTO), inductive loads, isolation and protection.

Design requirements

Digital output module designs often require:

  • Highly-efficient isolated power supply.
  • Advanced protection and diagnostics.
  • Driving capabilities at 24-V nominal voltage.

24-V input power protection

close

The 24V Input Power Protection protects systems powered from a nominal 24V against a combination of Over/under voltage, over current protection, miss-wire protection (reverse polarities) and inrush current protection. Traditionally this has been implemented with discrete components like diodes, fuses and PTC. Increasing protection requirements as well as higher efficiency requirements makes E-fuse, Hotswap and ideal diode solutions like offered by Texas Instruments attractive.
