Description

The LTC4368HDD-2#PBF is a robust overvoltage (OV) and undervoltage (UV) protection controller from Analog Devices. It safeguards sensitive circuits by disconnecting the load during voltage faults (up to 80V) using an external N-channel MOSFET.
Key features:
- Wide input range: 4V to 80V.
- Adjustable thresholds: OV/UV limits set via resistors.
- Fast response: <1µs reaction to transient spikes.
- Reverse-voltage protection: Withstands -40V without damage.
- Low quiescent current: 12µA in normal operation.
Packaged in a 10-lead DFN, it suits automotive, industrial, and power distribution systems. The "-2" variant offers a fixed 5ms fault recovery delay.
Applications:
- Load protection in 12V/24V systems.
- Surge suppression in harsh environments.
For details, refer to the datasheet.
