High-end driver based on L6370Q

STEVAL-IFP020V1

Overview

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_CCor 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.
