250mA to 2.5A Adjustable Current-Limit Switches
ABSOLUTE MAXIMUM RATINGS
(Voltages referenced to GND.)
IN, EN, EN, FLAG, OUT, and SETI to GND.............-0.3V to +6V
Current into Any Pin (Except IN, OUT)............................ Q20mA
OUT Short Circuit to GND.................................Internally Limited
Continuous Power Dissipation (TA = +70NC)
TDFN (derate 11.9mW/NC above +70NC).....................954mW
Operating Temperature Range........................... -40NC to +85NC
Storage Temperature Range............................. -65NC to +150NC
Junction Temperature......................................................+150NC
Lead Temperature (soldering, 10s).................................+300NC
Soldering Temperature (reflow).......................................+260NC
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.
PACKAGE THERMAL CHARACTERISTICS (Note 1)
TDFN
Junction-to-Ambient Thermal Resistance (BJA)...... +83.9NC/W
Junction-to-Case Thermal Resistance (BJC).............. +37NC/W
Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-lay-
er board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
ELECTRICAL CHARACTERISTICS
(VIN = +2.3V to +5.5V and TA = -40NC to +85NC, unless otherwise noted. Typical values are at VIN = +3.3V, CIN = 1FF, COUT = 1FF,
RSETI = 100kI., TA = +25°C.) (Note 2)
