The MAX812LEUS comes in a SOT-23-4 surface-mount package (also referred to as TO-253-4).
It is not qualified to AEC-Q100, so it is not the first choice for under-hood automotive or engine-bay applications. For a 5V rail in a control cabinet or a base station power supply, the temperature range is sufficient.
The part is RoHS non-compliant. Verify your assembly line's exemption status if you require RoHS compliance.
The reset threshold voltage is 4.63V, suitable for monitoring a nominal 5V supply rail.
It goes high when the monitored voltage drops below the threshold and stays high for the 140ms timeout after the voltage recovers.
The reset timeout is 140ms minimum. This ensures the supply and oscillator stabilize before the processor is released from reset.
