VNH7100BAS - Automotive Full Bridge Motor Driver
VNH7100BAS
High current, integrated H-Bridge driver for DC motors with control circuit and power drivers in a single package
The latest series of integrated H-Bridge drivers built on VIPower M0-7 technology offer higher power density, greater accuracy in critical diagnostics, and new protection features. This series covers a wide spectrum of RDS(on) values (8 mΩ up to 200 mΩ per bridge) and package options, ensuring design scalability. Key features include loss-less built-in load current sensing, operation down to 3 V, programmable latch-off operation, ultra-low quiescent current, PWM up to 20 KHz, and many more.
VNH7 Family Allows a Compact Design
Thanks to very small packages and high integration, these devices allow the implementation of compact and reliable solutions for automotive DC motor control applications. The SO-16N is a full plastic triple-island package and has a body size of only 38 mm2. The VNH7070AS and VNH7100AS are housed in this package, combining small size with good thermal performance and at very reasonable price. The PowerSSO-36 triple island has three exposed pads offering optimized thermal performance. This package also houses the VNH7040AY, a device able to address motors operating at up to 60 W.
