  • Maximum Continuous Output Current: 1A
  • Overvoltage Protection Threshold: Adjustable up to 28V
  • Reverse Polarity Protection: Yes
  • Quiescent Current: 20µA (typical)

Detailed Pin Configuration

The MAX5904ESA+ features the following pin configuration:

  1. VIN: Input voltage pin
  2. GND: Ground pin
  3. VOUT: Output voltage pin
  4. EN: Enable pin
  5. FLT: Fault indicator pin

Functional Features

  • Overvoltage protection: The MAX5904ESA+ safeguards the connected device by monitoring the input voltage and disconnecting it when it exceeds the set threshold.
  • Overcurrent protection: It limits the output current to prevent damage to the device during excessive load conditions.
  • Reverse polarity protection: The IC prevents damage caused by incorrect power connections by blocking the current flow.
  • Fault indication: The FLT pin provides a signal when a fault condition occurs, allowing for quick diagnosis and troubleshooting.

Advantages and Disadvantages

Advantages
