Description

General part information

MP1921 Series

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 150uA Quiescent Current UVLO for Both High Side and Low Side In SOIC8E, SOIC-8, 3×3mm QFN8, 3×3mm QFN9 and 4x4mm QFN10 Packages
