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. Magnias parts are halogen-free and RoHS compliant as standard, which supports green-supply-chain mandates in EU and Japanese industrial markets.
Application areas
PLC digital I/O module
- IEC 61000-4-5 surge TVS (24V class)
- Channel-protection ESD array
- Reverse-polarity MOSFET for the 24V input
- Open-drain wire-OR INT buffer
Sensor signal conditioning
- Ultra-low-noise LDO, about 10 µVRMS, for reference rails (PSR9032 / PSR2050)
- Comparator (window detection)
- Low-leakage Schottky
DIN-rail power supply
- 650V / 800V high-voltage MOSFET (primary)
- Synchronous rectifier MOSFET (60V / 100V)
- Buck for 24V / 48V rails, 4.5V to 60V input (MI2613B-S6)
- Wide-input LDO (housekeeping rail)
- Surge TVS on AC input
Industrial Ethernet / fieldbus
- Asymmetric protection for RS-485, -7V / 12V lines (PT0712JL)
- CAN / DeviceNet ESD (PCAN2493F-T3)
- CMF + ESD common-mode filter
- Level shifter (3.3V ↔ 1.8V management)
- PoE housekeeping LDO, up to 100V input (PSR10005)
