Power Features & Applications
- +5.5 V to +72 V supply voltage range covers automotive, industrial and telecom protection rails
- Fast gate shutoff during overvoltage events with 100 mA gate-sink capability
- Internal charge-pump circuit ensures 10 V gate-to-source enhancement for low external FET RDS(on)
- Adjustable overvoltage and undervoltage thresholds tailor protection to each supply rail
- External nMOSFET latches off after an overvoltage condition to isolate the load
- Thermal-shutdown protection with -40°C to +125°C operating range for harsh environments
- 3×3 mm TDFN package minimizes board area in high-voltage protection stages
