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 Drives N-Channel MOSFET Half Bridge bridge, N-channel power MOSFET driver. Its low 120V V Voltage Range BST side and high side driver channels are On-Chip Bootstrap Diode independently controlled and matched with a time Typical 16ns Propagation Delay Time delay of less than 5ns. Under-voltage lockout on Less Than 5ns Gate Drive Matching both high side and low side supplies force their Drives 1nf Load with 12ns/9ns Rise/Fall outputs low in case of insufficient supply. The Times with 12V VDD integrated bootstrap diode reduces external TTL Compatible Input component count. Less Than 150 A Quiescent Current UVLO for Both High Side and Low Side In SOIC8E, SOIC-8, 33mm QFN8, 33mm 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.
