Toshiba TLP5814H
Gate driver photocoupler
Toshiba’s TLP5814H gate driver photocoupler is designed for safe, efficient switching of Si & SiC MOSFETs as well as IGBTs in harsh industrial environments. It features a built-in active Miller clamp to prevent self-turn-on in fast switching, high CMTI for noise immunity, and rail-to-rail output with +6.8/-4.8A peak current. Its compact SO8L package and 8mm creepage simplify layout and complies with relevant safety standards.
Key features
- Built-in active Miller clamp (0.69Ω, 6.8A): Prevents self-turn-on, saves space
- ±70kV/μs CMTI (min): Ensures stable operation for high-speed switching
- Rail-to-rail output (+6.8/-4.8A): Enhances switching performance
- Faraday shield: Improves signal integrity in high dV/dt applications
- Wide temperature range (-40°C to 125°C): Reliable in harsh conditions
- Compact SO8L package (5.85 × 10 × 2.1mm): Saves board space
- 8mm creepage distance: Meets high insulation requirements
- No external Miller clamp needed: Reduces system cost, board space and complexity
Applications
- Industrial inverters: Safe and efficient SiC switching
- UPS systems: Reliable gate drive under high stress
- PV inverters: Compact and robust insulation solution
- Motor drives: Enhanced control and noise immunity
- Power converters: Simplified design with fewer components
