LTC4367CMS8-1#PBF

LTC4367 is a 100V overvoltage, undervoltage and reverse supply protection controller. It protects applications where power supply input voltages may be too high, too low or even negative. It does this by controlling the gate voltages of a pair of external N-channel MOSFETs to ensure that the output stays within a safe operating range. It withstands voltages between -40V and 100V and has an operating range of 2.5V to 60V, while consuming only 70µA in normal operation. Two comparator inputs allow configuration of the overvoltage (OV) and undervoltage (UV) set points using an external resistive divider. A shutdown pin provides external control for enabling and disabling the MOSFETs as well as placing the device in a low current shutdown state. It is used in applications such as portable instrumentation, industrial automation, automotive surge (load dump) protection, network equipment.
