2 / 22 page 1V to 13.2V, n-Channel Hot-Swap Controllers Require No Sense Resistor 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS ELECTRICAL CHARACTERISTICS (VCC, EN (MAX5924/MAX5925), EN1 (MAX5926) = +2.25V to +13.2V; EN2 (MAX5926) = 0V; VS (see Figure 1) = +1.05V to VCC; TA = -40°C to +85°C, unless otherwise noted. Typical values are at VCC = 5V, RL = 500 Ω from OUT to GND, CL = 1µF, SLEW = open, TA = +25°C, unless otherwise noted.) (Note 1) Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. (All voltages referenced to GND, unless otherwise noted).
