- Adjustable overvoltage threshold protects downstream circuitry in 2.7 V to 23 V supply systems without external comparators
- Single-channel architecture in a 10-pin VQFN footprint minimizes board space for space-constrained power-path designs
- Integrated input fault detection reduces external component count compared to discrete protection circuits
- RoHS-compliant lead-free packaging introduced in 2020 for modern industrial and communications equipment
Applications
TPS259474LRPWR is ideal for protecting sensitive downstream components in industrial power distribution, server infrastructure, and communications equipment from input overvoltage and fault conditions. Its 2.7 V to 23 V input range covers common 3.3 V, 5 V, 12 V, and 19 V supply rails used in embedded computing and networking hardware. The adjustable threshold makes it adaptable to a wide variety of fault protection schemes without requiring discrete resistor networks or additional ICs.

Frequently Asked Questions
Over what supply voltage range does TPS259474LRPWR provide fault protection, and how is the threshold set?
TPS259474LRPWR operates from 2.7 V to 23 V input and features an adjustable overvoltage threshold configurable via an external resistor divider. This flexibility lets designers protect 3.3 V, 5 V, 12 V, and 19 V rails with a single device while precisely tuning the fault trip point.
Which board-level package does TPS259474LRPWR use, and how does it benefit compact PCB layouts?
TPS259474LRPWR comes in a 10-pin VQFN (JESD-30 code S-PQCC-N10) package, which offers a very small PCB footprint compared to larger SOIC or TSSOP alternatives. This is advantageous in space-constrained designs such as blade servers, network switches, and portable industrial devices where every square millimeter matters.
How does TPS259474LRPWR simplify fault protection design compared to building a discrete solution with op-amps and MOSFETs?
By integrating the fault detection comparator, gate driver, and adjustable threshold logic into a single 10-pin package, TPS259474LRPWR eliminates the need for multiple discrete components across its 2.7 V to 23 V operating range. This reduces BOM count, minimizes board area, and shortens design time for input protection on single-channel power rails.
