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.
