Service - Coil Drivers with Protection - Brand [Weckway]

UGQ5140K is a low-power magnetic coil driver, such as a relay or solenoid. Its built-in Darlington power output can continuously absorb currents exceeding 300mA, and the internal protection circuit can limit surge currents and fault currents to approximately 900mA. The UGQ5140K includes a Hall voltage generator, operational amplifier, Schmitt trigger, regulator, and open collector Darlington output stage.

Main features:

Magnetic excitation power switch

● Temperature compensation for switch points

● High current absorption capacity

● Continuous 300mA

● Peak limit 900mA

● Output short circuit protection

Low static waiting current

● Built in clamp protection diode

● Power reverse polarity protection
