BL8598 - Adjustable Overvoltage Protector

General Description

The BL8598 overvoltage protection devices feature a low 180 (typ) RON internal FET and safeguards 2.2V to 28V systems from power supply overvoltage.

If the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent the output load circuits from damage.

Key Features

  • Overvoltage Protection up to 28V.
  • ±2.5% Accurate 6.75V OVLO Threshold.
  • Adjustable Overvoltage Protection Trip Level.
  • Integrated 180 n-Channel MOSFET Switch.
  • Automatic Overvoltage Protection Trip-Level Selection.
  • Internal 15ms Startup Delay.
  • Thermal Shutdown Protection.
  • Available in DFN2x2-8L Package.
  • Temperature Range: -40C~85C.

BL8598 Adjustable Overvoltage Protector with High Accuracy DESCRIPTION The BL8598 overvoltage protection devices feature a low 180 (typ) RON internal FET and safeguards 2.2V to 28V systems from power supply overvoltage. If the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent the output load circuits from damage. The overvoltage protection threshold can be adjusted with optional external resistors to any voltage between 4V and 8V. With the OVLO input set below the external OVLO select voltage, the BL8598 automatically choose the internal ±2.5% accurate trip thresholds. The internal overvoltage thresholds (OVLO) are preset to 6.75V typical. The BL8598 includes an internal thermal shutdown circuit which can protect against overcurrent events.
