LTC4365IDDB-1#TRMPBF

LTC4365-1 is an overvoltage, undervoltage and reverse supply protection controller 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. 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 provides status of the gate pin pulling low. A fault is indicated when the part is in shutdown or the input voltage is outside the UV and OV set points. Typical applications are portable instrumentation, laptops.

• Fast (1ms) recovery from fault
• No input capacitor or TVS required for most applications
• Wide operating voltage range from 2.5V to 34V at TA=25°C
• Reverse supply protection to –40V at TA=25°C, VIN=2.5V to 34V
• Input supply current is 25µA typical at active-low SHDN=2.5V, TA=25°C, VIN=2.5V to 34V
• VOUT input current is 100µA at active-low SHDN=2.5V, VIN=VOUT, TA=25°C. VIN=2.5V to 34V
• Input supply undervoltage lockout is 2.2V at VIN rising, TA=25°C, VIN=2.5V to 34V
• 8-lead (3mm × 2mm) plastic DFN package
• –40°C to 85°C temperature rating
