Ultra-Small, Hex Voltage,
Microprocessor Supervisor
_______________________________________________________________________________________ 3
Note 1: 100% production tested at T A = +25°C. Limits over temperature guaranteed by design.
Note 2: The devices are powered from IN1.
Note 3: Monitored IN1 voltage is also the device power supply.
Note 4: RESET output is guaranteed to be in the correct state for IN1 or IN2 falling down to 1V.
