The STEVAL-IFP020V1 demonstration board is 
based on the L6370Q, a single-channel high-side 
driver chip intended for driving resistive, inductive 
or capacitive loads in an industrial environment. It 
provides an embedded fast demagnetization 
feature for inductive load switch-off. 

The device evaluates load disconnection (during 
channel on-state), output short to V

CC

 or GND, 

overtemperature, undervoltage of supply voltage, 
and provides feedback to a control unit.

Integrating an extensive set of electrical 
protections makes the application safe and 
reliable for use in harsh conditions.

The STEVAL-IFP020V1 demonstration board is 
an example of application design using the 
L6370Q. It is used to guide the designer in 
choosing external components for applications 
while providing an appropriate PCB design.
