200 V GaN Gate Driver

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.

The MDC901-EVKHB evaluation kit enables easy design-in and validation of the MDC901.

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
