TPS25948 Overview
Key Specifications
Description
The TPS25948xx family of eFuses is a highly integrated, circuit-protection and power-management solution in a small package. The devices provide multiple protection modes that use few external components and are a robust defense against overloads, shor.
Key Features
- Wide operating input voltage range: 3.5V to 23V – 28V absolute maximum – Can be powered from either IN or OUT
- Integrated back-to-back FETs with low ONresistance: RON = 12.2mΩ (typ)
- Fast overvoltage protection – Adjustable overvoltage lockout (OVLO) with 1μs (typ) response time
- Overcurrent protection with load current monitor output (ILM) – Active current limit response – Adjustable threshold (ILIM) 1A–9A
- Fast-trip response for short-circuit protection – < 1μs (typ) response time – Adjustable and fixed thresholds
- Active high enable input with adjustable undervoltage lockout threshold (UVLO)
- Adjustable output slew rate control (dVdt)
- Overtemperature protection
- Digital outputs: Supply Good (SPLYGD/SPLYGD) and Fault Indication (FLT)
- UL 2367 recognition (planned)
