High side driver - 4 channels based on VN340
Features
■ Complies with IEC 61000-4-4 (4 kV), IEC
61000-4-5 (2 kV) and IEC 61000-4-6 (10 V)
■ 8 channels @ 0.5 A per channel
■ DC/DC converter
■ Excellent thermal behavior
■ Power supply up to 35 V
■ Very low standby current
Description
The purpose of this evaluation board is to
demonstrate the features of the VN340 high-side
driver. The application offers robustness and
complies with EMC industrial standards. It
implements short circuit/overload protection and
thermal management as well, achieving best-inclass MTBF values. The reference design is
suitable for use in programmable logic controllers
(PLCs). The digital outputs are compliant with IEC
standards.
