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
