BL8598

Adjustable Overvoltage Protector with High Accuracy

DESCRIPTION

FEATURES

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.



Overvoltage Protection up to 28V

±2.5% Accurate 6.75V OVLO Threshold

Adjustable Overvoltage Protection Trip Level

Integrated 180ꢀꢁ 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

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.

APPLICATIONS



Cell Phones

MP3 and MP4 players

PDAs and Palmtop Devices

BL8598 is available in DFN2x2-8L package.

TYPICAL APPLICATION

PIN OUT

BL8598

DFN2x2-8L

R1 and R2 are required only for adjustable OVLO;

otherwise, connect OVLO to GND.

*Connect exposed PAD to GND.
