Absolute Maximum Ratings

Note 1



Input Voltage to GND -------------------------------------------------------------------------------------------------------------------------------- 0.3V to 28V



BAT voltage GND -------------------------------------------------------------------------------------------------------------------------------------- - 5V to 7V



Other pin to GND ------------------------------------------------------------------------------------------------------------------------------------- 0.3V to 6.5V



Maximum Junction Temperature ----------------------------------------------------------------------------------------------------------------------- 125°C



Maximum Soldering Temperature (at leads, 10 sec) ------------------------------------------------------------------------------------------ 260°C



Storage Temperature --------------------------------------------------------------------------------------------------------------------------- -55℃ to 150°C

Note 1.

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.

Thermal Information

Note 2



Maximum Power Dissipation ( PD,TA=25°C) -------------------------------------------------------------------------------------------------------- 1.5W



Thermal Resistance (JA) -------------------------------------------------------------------------------------------------------------------------------- 65℃/W

Note 2.

JA is measured in the natural convection at TA = 25C on a high effective thermal conductivity four-layer test board of JEDEC 51

thermal measurement standard.

ESD Susceptibility

Note 3



HBM(Human Body Mode) ------------------------------------------------------------------------------------------------------------------------------------ 2KV



MM(Machine Mode) -------------------------------------------------------------------------------------------------------------------------------------------- 200V

Note 2.

Devices are ESD sensitive. Handling precaution is recommended
