Description
TPS24740RGER is a Texas Instruments device from the TPS24740 family—a high-side load switch designed to protect and control power rails. It provides built‑in current limiting, soft‑start to limit inrush, overcurrent and thermal protection, undervoltage lockout, and fault/status reporting. This enables safe startup/shutdown and protection for multiple loads or rails in systems such as telecom, data centers, industrial, and embedded equipment. The RGER suffix indicates RoHS-compliant, green packaging with tape‑and‑reel. Typical usage includes protecting a supply rail during board insertion, sequencing rails, and guarding against shorts or overloads while offering simple enable/diagnostic signals to a host controller.
Features
TPS24740RGER Features (concise):
- 40-V max input voltage with four high-side switches (hot-swop protection)
- Per-channel programmable current limit with integrated FETs
- Soft-start / slew-rate control to limit inrush current
- Overcurrent/short-circuit protection with hiccup auto-retry
- Overvoltage, undervoltage, and thermal protection (shutdown/limit)
- Reverse-current protection to prevent backfeed
- Fault/Status reporting pins for each channel (diagnostics)
- Enable/disable control and basic sequencing options
- Compact packaging (RGER variant) suitable for space-constrained designs
Note: Specifics (exact current limits, timing, and pinout) are defined in the TI datasheet for TPS24740RGER.

Application
TPS24740RGER is a hot‑swap controller with current limit and protection for high‑side switches. It is used to safely insert/remove boards and protect DC rails from inrush, overcurrent, and fault conditions. Typical applications include 12–60 V DC rails in telecom and data‑com equipment, servers and storage, network switches, backplanes and redundant power supplies, and industrial automation systems that require soft-start, UVLO/OVLO protection, and thermal shutdown.
Package
TPS24740RGER is in an 8-pin VSSOP package (VSSOP-8), typically RoHS-compliant.
