Applications
TPS272C45CRHFR is designed for industrial automation, factory I/O modules, and building-control systems that need reliable switching of inductive or resistive loads up to 45 V. Its dual-channel architecture allows simultaneous independent control of two solenoids, relays, or LED strings from a single device. Integrated multi-fault protection simplifies system-level safety compliance and reduces external component count.

Frequently Asked Questions
What load voltage and channel count does TPS272C45CRHFR support in an industrial I/O module?
TPS272C45CRHFR supports up to 45 V load voltage across 2 independent high-side channels, making it well-suited for 24 V industrial control systems that need to switch solenoids, relays, or actuators. The dual-channel design lets a single device replace two separate discrete switches, reducing board area by up to 40% while retaining per-channel fault reporting.
How does the integrated current-sense feature of TPS272C45CRHFR help with predictive maintenance?
TPS272C45CRHFR provides an analog current-sense output proportional to load current on each channel, allowing the host MCU to monitor actual load draw without external shunt resistors. By comparing sampled current values over time, firmware can detect gradual degradation in solenoid coils or relay windings before a hard failure occurs, reducing unplanned downtime in 24 V industrial automation lines.
Which protection mechanisms are built into TPS272C45CRHFR, and how do they interact during an inductive load transient?
TPS272C45CRHFR integrates transient suppression, over-current limiting, over-voltage clamp, under-voltage lockout, and thermal shutdown. During an inductive load transient, the over-voltage clamp absorbs the back-EMF spike, protecting both the switch and the 45 V bus. If current exceeds the set threshold, the device reduces gate drive to limit current before thermal shutdown activates at approximately 150°C junction temperature, allowing controlled fault recovery.
