Fs7867s is a voltage detection chip used for power supply voltage monitoring of digital system

summary
Microprocessor voltage detection reset core
FS7867S It is a voltage detection chip applied to the voltage monitoring of power supply of digital system , It can work within the industrial standard temperature range .
FS7867S Generate a reset signal , When the system power supply voltage drops to the set value, the reset signal becomes low , When the system power supply voltage returns to the set value
The chip will be at least 140ms Set the reset signal high after the delay time of .FS7867S The series products can provide any set detection voltage value required by customers
At present, we will provide 7 Targeted 5.0V, 3.3V, 3.0V and 2.5V Standard industrial voltage monitoring value of four types of power supply voltage .
FS7867S Provide the output stage of push-pull structure , When the voltage to be monitored is higher than the set voltage value, reset the output high level .
The jitter and burr of fast power transient will be filtered out by this chip without causing malfunction , At the same time, even if the power supply voltage is as low as L0V It can also ensure normal
Output logic and performance indicators .
FS7867S Provide compact 3 Foot packaging form S OT-23 and SOT-23-3L.
