Descriptions
The DIO1280B features a low- RON internal FET
and an operating range of 2.5 VDC to 25 VDC
(absolute maximum of 30 VDC). An internal clamp
is capable of shunting surge voltages>100V,
protecting downstream components and
enhancing system robustness. The DIO1280B
features over-voltage protection that powers
down the internal FET if the input voltage exceeds
the OVP threshold. The OVP threshold is
adjustable with optional external resistors.
Over-temperature protection also powers down
the device at 130℃ (typical). Exceptionally low
off-state current (<1μA maximum) facilitates
compliance with standby power requirements.
