• Manufacturer Part Number: MAX6886
• Description: Pin-Selectable, Hex Power-Supply Supervisory Circuit
• Manufacturer: MAXIM [Maxim Integrated Products]

Set the RESET time delay by connecting a capacitor
from SRT to GND using the following equation:
where t
SRT to V
RESET is open-drain and requires an external pullup
resistor. RESET remains low for 1V ≤ V

For better noise immunity, bypass each of the voltage-
detector inputs to GND with 0.1µF capacitors installed
as close to the device as possible. Bypass V
DBP to GND with 1µF capacitors installed as close to
the device as possible.
