Maxim Integrated MAX14919 | Demoboard MAX14919EVKIT

Industrial-Protected Quad-Channel Low-Side Switch

Overview

TopologyPush-Pull Converter symmetrical isolated
Input voltage3-5 V

Description

The MAX14919 evaluation kit (EV kit) provides a proven design to evaluate the MAX14919 industrial-grade quad low-side switch with 140mΩ (typ) RON and ±1kV/42Ω surge protection.The MAX14919 EV kit features an isolated power and signal interface to provide pin-level control of the four lowside switches in the MAX14919. The EV kit also features reverse-current detection to prevent damage caused by miswiring faults at output and return terminals.

Features

  • Robust Operation with a Wide Range of Input Voltages and Load Conditions
  • Surge Protection with Up To ±1kV IEC61000-4-5 at Output to Ground
  • LED Indication of Fault and Reverse-Current Detect Conditions
  • Multiple Fault-Condition Indications
  • Reverse-Current Detection
  • Under voltage Lockout on V5 Output
  • Short Detection on RCLIM Control Input
  • Thermal Shutdown Fault
  • Includes a FET for Output Reverse-Current Protection -Inrush Current Control to Allow up to 2x the Maximum Load Current
  • Resistor-Selectable Options to Set Maximum Allowable Load Current
  • +1.8V to +5.5V Wide Logic-Voltage Range
  • +3V to +5.5V Isolated Supply Input Range
  • Proven PCB Layout
  • Fully Assembled and Tested

Typical applications

  • Industrial Digital Outputs, Relay and Solenoid Drivers, PLC and DCS Systems, Motor Controll
