DC2417A-B

DC2417A-B is a LTC4367IMS8-1 UV, OV and reverse supply protection with 0.5ms fault recovery demo board. 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 (active low) SHDN pin disables the MOSFETs and places the LTC4367 in a low current shutdown state. The (active low) FAULT pin asserts when the controller is in the shutdown mode or when the input voltage is outside of the UV/OV window.

• Input voltage of 2.5 to 60V at operating range, -40 to 100V at protection range
• 1.8 to 2.4V at input supply undervoltage lockout at VIN rising
• 90µA max input supply current; on (active low SHDN = 2.5V)
• 5.75 to 6.17V board UV range
• 14.44 to 15.47V board OV range
