LTC4367CMS8#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. The LTC4367 withstands voltages between –40V and 100V and has an operating range of 2.5V to 60V. 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. A fault output indicates that the GATE pin is pulling low when the part is in shutdown or the input voltage is outside the UV and OV set points. Applications include portable instrumentation, industrial automation, automotive surge (load dump) protection, network equipment.
