Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to GND unless otherwise
specified.
Note 3: Internal clamps limit the DRN pin to a minimum of 10V above the
OUT and SNS pins.
Note 4: Internal clamps limit the GATE pin to a minimum of 10V above the
OUT pin or VCC pin, or 50V (SEL = VCC) or 31.5V (SEL = GND) above the
GND pin (LTC4380-1/LTC4380-2). Driving this pin to voltages beyond the
clamp may damage the device.
Note 5: Total supply current is the sum of the current into the VCC, OUT,
SNS and DRN pins.
Note 6: Operating voltage is limited by the maximum GATE voltage of 86V.
