MDC901 High Performance, 200 V Gate Driver IC
The MDC901 is a non-isolated high-side and low-side gate driver with floating regulators and integrated level shifting, specifically developed to reliably drive enhanced mode GaN devices.
Key Features
- Unprecedented gate drive strength up to 9A
- Separate pull-up and pull-down outputs for gate drive tuning
- Programmable true floating regulators (5 or 6V), protecting the sensitive GaN gate against overcharging.
- Integrated charge pump for 100% duty cycle applications
- High efficiency integrated bootstrap diodes
- Automatic closed-loop and programmable dead-time
- Integrated 5V regulator enables single supply voltage operation
- 200V operation, supporting negative source-voltage transients down to -4V
Benefits
- Slew rate capability in excess of 100V/ns
- Fast design-in thanks to EVB layout examples
- Diagnostics:
- Gate signal monitoring outputs
- Die temperature monitoring
- Undervoltage lockout outputs for HS and LS
- Highly compacted solution compared to other solution with the same functionality
- Separate turn-on/off programmable feed-forward dead-time
- All-in one solution : integrated 5V linear regulators for I/O
- Propagation delay : 30ns, with 1ns delay matching between HS and LS
- Tunable dead-time for optimal switching match
Applications
- Highly-efficient server PoL converters
- High voltage pulsers for MEMS (ultrasound transducers, MEMS switches)
- DC-DC converters
- AC-DC converters
- Class-D audio amplifiers
Use Cases
- Data & server centers
- High quality speaker systems
- High precision motor drives
MDC901 Evaluation Kit
We have developed a high-quality evaluation board to give all power designers a head start for designing-in the MDC901 GaN gate driver. The MDC901-EVBHB is a step-down converter board in a half-bridge configuration for out-of-the-box device characterization and testing.
