Dual, 3mm x 3mm, 1.2A/Programmable-Current
USB Switches with Autoreset
ABSOLUTE MAXIMUM RATINGS
IN_, ON_, OUT_, ISET, FLT_ to GND........................-0.3V to +6V
IN_ to OUT_ (when disabled) (Note 1) ........................-6V to +6V
IN_ to OUT_ (when enabled) (Note 2) ............-1.6A to +1.6A_RMS
FLT_ Sink Current................................................................20mA
Continuous Power Dissipation (T_A = +70°C)
10-Pin TDFN 3mm x 3mm
(derate 24.4mW/°C above +70°C) .............................1952mW
Operating Temperature Range ...........................-40°C to +85°C
Junction Temperature ......................................................+160°C
Storage Temperature Range .............................-65°C to +150°C
Lead Temperature (soldering, 10s) .................................+300°C
Note 1: Reverse current (current from OUT_ to IN_) is blocked when disabled.
Note 2: Forward current (current from IN_ to OUT_) is internally limited. Reverse current, from OUT_ to IN_, is not limited when the
device is enabled and must be kept below 1.5A_RMS to prevent permanent device damage. When the MAX1558/MAX1558H
are disabled, the switch turns off and reverse current is internally blocked.
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.
ELECTRICAL CHARACTERISTICS
(V_INA = V_INB = 5V, V_ONA = V_ONB = 0V (MAX1558), V_ONA = V_ONB = 5V (MAX1558H), R_ISET = 26kΩ to GND, T_A = 0°C to +85°C,
unless otherwise noted. Typical values are at T_A = +25°C.) (Note 3)
