AEC-Q100 Qualified for Automotive Applications

The LTC4367 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, 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. 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.

The LTC4367 has a 32ms turn-on delay that debounces live connections and blocks 50Hz to 60Hz AC power. For fast recovery after faults, the LTC4367-1 has a reduced turn-on delay of 500μs.

Product Details

Demonstration circuit 2417A is intended to demonstrate the performance of the LTC4367 100V overvoltage (OV), undervoltage (UV), and reverse supply protection controller.

This controller protects circuits from input voltages that may be too high, too low or negative. It operates by controlling the gates of two back-to-back connected N-channel MOSFETs to keep the output in a safe range. The UV and OV setpoints are configured by the resistive divider on the UV and OV inputs. Asserting the SHDN pin disables the MOSFETs and places the LTC4367 in a low current shutdown state. The FAULT pin asserts when the controller is in the shutdown mode or when the input voltage is outside of the UV/OV window.
