• Manufacturer Part Number: MAX5008
• Description: MAX5008 Regulated 5V Usb Charge Pump With Programmable Current Limit
• Manufacturer: Maxim Integrated Products

ELECTRICAL CHARACTERISTICS (continued)
(V
Typical values are at T
Note 1: When the input exceeds 4.25V, the power dissipation on the chip exceeds the maximum rating if the output current is 125mA.
Note 2: The MIN/MAX limits are 100% production tested at +25°C and +70°C, and guaranteed by design at 0°C.
Note 3: I
Note 4: The delay from the fault event to the assertion of FAULT. Fault delays are specified with either a current fault or a voltage
Note 5: The delay from the removal of the fault event to the deassertion of FAULT.
