MAX5924 MAXIM [Maxim Integrated Products], MAX5924 Datasheet - Page 2

• Manufacturer Part Number: MAX5924
• Description: 1V to 13.2V, n-Channel Hot-Swap Controllers Require No Sense Resistor
• Manufacturer: MAXIM [Maxim Integrated Products]

ABSOLUTE MAXIMUM RATINGS
(All voltages referenced to GND, unless otherwise noted).
V
GATE*.....................................................................-0.3V to +20V
All Other Pins .........-0.3V to the lower of (V
SC_DET Current (200ms pulse width, 15% duty cycle) ...140mA
Continuous Current (all other pins) .....................................20mA
1V to 13.2V, n-Channel Hot-Swap Controllers
Require No Sense Resistor
*GATE is internally driven and clamped. Do not drive GATE with external source.
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.
