MAX670 Maxim, MAX670 Datasheet - Page 3

• Manufacturer Part Number: MAX670
• Description: Low-Voltage / SOT23 P Supervisors with Power- Fail In/Out / Manual Reset / and Watchdog Timer
• Manufacturer: Maxim

ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: 100% production tested at T
Note 2: The devices are powered from IN2 or V
Note 3: The RESET output is guaranteed to be in the correct state for IN1 or IN2 down to 1V.
Note 4: Monitored IN2 voltage (3.3V, 3.0V) is also the device power supply. Supply current splits as follows: 25µA for the resistor
