MP1921A 100V, 2.5A, High Frequency Half-Bridge Gate Driver The Future of Analog IC Technology DESCRIPTION FEATURES The MP1921A is a high-frequency, 100V, half bridge, N-channel power MOSFET driver. Its low side and high side driver channels are independently controlled and matched with a time delay of less than 5ns. Under-voltage lockout on both high side and low side supplies force their outputs low in case of insufficient supply. The integrated bootstrap diode reduces external component count.           Drives N-Channel MOSFET Half Bridge 120V VBST Voltage Range On-Chip Bootstrap Diode Typical 16ns Propagation Delay Time Less Than 5ns Gate Drive Matching Drives 1nf Load with 12ns/9ns Rise/Fall Times with 12V VDD TTL Compatible Input Less Than 150A Quiescent Current UVLO for Both High Side and Low Side In SOIC8E, SOIC-8, 3×3mm QFN8, 3×3mm QFN9 and 4x4mm QFN10 Packages APPLICATIONS      Telecom Half Bridge Power Supplies Avionics DC-DC Converters Two-Switch Forward Converters Active Clamp Forward Converters DC Motor Drivers All MPS parts are lead-free and adhere to the RoHS directive.
