MTL4524 – MTL5524 SOLENOID/ALARM DRIVER switch operated with override, IIC

MTL4524 – MTL5524 SOLENOID/ALARM DRIVER switch operated with override, IIC

The MTLx524 enables an on/off device in a hazardous area to be controlled by a volt-free contact or logic signal in the safe area. It can
drive loads such as solenoids, alarms, LEDs and other low power devices that are certified as intrinsically safe or are classified as nonenergy storing simple apparatus.
The MTL4524 allows a second safe-area switch or logic signal to be connected enabling the output to be disabled to permit, for example, a
safety system to override a control signal. The MTL5524 has its phase reversed by connecting a wire link between pins 8 and 9.

Current limit: 48mA minimum
Output ripple
< 0.5% of maximum output, peak-to-peak
Control input
Suitable for switch contacts, an open collector transistor or logic drive
0 = input switch closed, transistor on or <1.4V applied 1 = input switch open, transistor off or >4.5V applied
Override input on MTL4524
An open collector transistor or a switch connected across the terminals can
be used to turn the output off whatever the state of the control input
0 = transistor on or switch closed
1 = transistor off or switch open
