Description
The MLX16305 is designed to diagnose the state of remote interlock switches in automotive safety applications. Its high accuracy allows it to be applied in a broad range of related automotive and industrial applications using current modulated sensors and switches.

FEATUREs and Benefits
• 6 sense Channels
• Large supply current + supply voltage range for maximum contact cleaning
• Applicable with all 2-wire Hall effect switches
• Diagnoses open wires, shorts to Supplies and shorts between wires
    o Current and Voltage measurement mode
    o High measurement accuracy: 5%
• Current limited supply regulator
• Automotive qualified (40V Load Dump)
• Over-temperature detection
• Small Package: narrow body (150mils) SO16, RoHS compliant
