Multi-powerSO™-30

The VNH5 series of H-bridges offers multiple

solutions for actuating a wide range of

DC motors, especially for automotive

applications. Today, environmental

regulations drive the market towards lighter

and smaller silicon drivers ensuring reduced

CO

2 emissions. The VNH5 series, compared

to a mechanical relay or multi-package

solid-state solutions, is an eco-friendly

and cost-effective approach integrating

the power stage (two high-side and two

low-side switches) plus dedicated control

and diagnostic functions within the same

package.

VNH5 products can be easily driven by a

microcontroller through dedicated input pins,

compatible with 3 V CMOS. These define

motor direction (clockwise or counter-

clockwise), speed (PWM controlled) and

active braking. An embedded non-dissipative

current sense output enables torque

control and load disconnection detection.

Its advanced diagnostics and protection

functions are ideal for robust applications

able to protect themselves against hazardous

conditions.
