Industrial Automation Control
Robust ICs for PLC I/O, sensor modules, DIN-rail power, and industrial communications
Industrial automation lives at the boundary of high voltages (24V / 48V bus), long cable runs (ESD / surge), and harsh thermal environments. Magnias supplies ICs and discretes that meet these constraints: TVS arrays sized for IEC 61000-4-5 surge events, MOSFETs with wide VGS and high SOA, low-IQ LDOs for sensor modules running on backup batteries, and small-signal logic for fieldbus and HMI interfaces. Many parts are available in halogen-free (-H suffix) variants to meet green-supply-chain mandates in EU and Japanese industrial markets.
Application areas

- IEC 61000-4-5 surge TVS (24V class)
- Channel-protection ESD array
- Isolated load switch
- Open-drain wire-OR INT buffer
Sensor signal conditioning
- Ultra-low-noise LDO (sub-µV reference rail)
- Comparator (window detection)
- Low-leakage Schottky
- Photodiode bias LDO
DIN-rail power supply
- 650V / 800V high-voltage MOSFET (primary)
- Synchronous rectifier MOSFET (60V / 100V)
