TPS25982
Overview
The TPS25982 family of eFuses is a highly integrated circuit protection and power management solution in a small package. The devices are operational over a wide input voltage range.
- 1 Wide input voltage range: 2.7 V to 24 V - 30-V Absolute maximum
- Low On-Resistance: RON = 2.7-mΩ typical
- Adjustable current limit threshold - Range: 2 A to 15 A - Accuracy: ± 8% (typical for ILIM > 5 A)
- Circuit breaker and current limiter options
- Adjustable over-current blanking timer - Handles load transients without tripping
- Accurate current monitor output - ± 1.5% (typical at 25 °C for IOUT > 3 A)
- 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 < 400-ns typical - Tested against 1 million power-into-short events - Immune to line transients - no nuisance tripping
- Adjustable output slew rate (dVdt) control
- Adjustable undervoltage lockout
