• Manufacturer Part Number: SMM105
• Description: Single-channel Supply Voltage Marginer And Active Dc Output Controller Microelectronics, Inc.
• Manufacturer: SUMMIT Microelectronics, Inc:

Note 1 – The Base DC Hysteresis voltage is measured with a 1.25V external voltage source. The resulting value is determined by subtracting
Threshold Low from Threshold High, V
Hysteresis is derived from the equation: (V
(2.5V/1.25V)(0.003V)=6mV.
ABSOLUTE MAXIMUM RATINGS

Note - The device is not guaranteed to function outside its operating
rating. Stresses 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
outside those listed in the operational sections of the specification is
not implied. Exposure to any absolute maximum rating for extended
periods may affect device performance and reliability. Devices are
ESD sensitive. Handling precautions are recommended.
