7 Specifications

7.1 Absolute Maximum Ratings

over operating free–air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VIN, ON Input voltage –0.3 4 V
VOUT Output voltage –0.3 4 V
IMAX Maximum continuous switch current at TA = 60°C 3 A
IPLS Maximum pulsed switch current, 100–μs pulse, 2% duty cycle 4 A
TJ Junction temperature 125 °C
Tstg Storage temperature –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.

7.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human–body model (HBM), per ANSI/ESDA/JEDEC JS–001(1) ±2000 V
Charged–device model (CDM), per JEDEC specification JESD22–C101(2) ±1000
(1) JEDEC document JEP155 states that 500–V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500–V HBM is possible with the necessary precautions.
(2) JEDEC document JEP157 states that 250–V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250–V CDM is possible with the necessary precautions.

(1) Turn-off time and fall time are dependent on the time constant at the load. For TPS22925BN and TPS22925CN, there is no QOD. The time constant is RL× CL. For TPS22925B and TPS22925C, internal pull-down resistor RPD is enabled when the switch is disabled. The time constant is (RPD || RL) × CL.
