TPS25983 Overview
Description
The TPS25983 family of eFuses is a highly-integrated circuit protection and power management device in a small package. The devices are operational over a wide input voltage range.
Key Features
- Wide input voltage range: 2.7V to 26V – 30V absolute maximum
- Low on-resistance: RON = 2.7mΩ typical
- Adjustable current limit threshold – Range: 2A to 20A – Accuracy: ±8% (typical for ILIM > 5A)
- Circuit breaker and current limiter options
- Adjustable overcurrent blanking timer – Handles load transients without tripping
- Accurate current monitor output – ±1.5% (typical at 25°C for IOUT > 3A) – ±3% (maximum for IOUT > 3A)
- User configurable fault response – Latch-off or auto-retry – Number of retries (finite or indefinite) – Delay between retries
- Robust short-circuit protection – Fast-trip response time < 400ns typical – Immune to line transients – no nuisance tripping
- Adjustable output slew rate (dVdt) control
- Option to drive external FET for reverse current blocking in disabled/OFF state
