3 Description

The TPS274C65CP device is a quad-channel smart

high-side switch designed to meet the requirements

of industrial control systems. The low 72-mΩ RDSON

minimizes device power dissipation even when

providing large output load current. The device

integrates protection and diagnostic features to

ensure system protection even during harmful events

like short circuits or load failures. The device protects

against faults through a reliable current limit which is

adjustable from 300 mA to 1.9 A to provide protection

regardless of output load current.

The TPS274C65CP has an internal regulator to

create voltage for internal rails. Additionally, a VDD

pin is provided to allow the use of external VDD

supply which must be derived from the VS to

reduce the power dissipation. The comprehensive

fault reporting include a dedicated VS_FLT pin to

indicate the VS undervoltage, and separate fault pin

STx to indicate the faults happening in each channel.

The TPS274C65CP is available in a small 6-mm ×

6-mm VQFN package with 0.5-mm pin pitch, which

minimizes design PCB footprint.
