Temperature grade and deployment environment
Rated for -40°C to 125°C ambient, this supervisor covers the full industrial temperature span. The 125°C upper limit allows placement near a hot processor or power module without derating concerns.
Output type and what it demands from your board
The reset output is active-low, open-drain. That means the output pin pulls to ground when reset is asserted, and floats when reset is released. You must provide an external pull-up resistor to the logic supply (typically 10kΩ to 100kΩ) to get a valid high level. The open-drain topology is useful because it lets you wire-OR the reset signal with other supervisors or a manual reset button — any device pulling the line low forces a system reset. It also means the output voltage is not limited by the supervisor's supply; you can pull up to a different voltage rail if the downstream logic requires it.
Package and footprint reality
Housed in a SOT-143-4 package, this is a four-pin surface-mount part with a 1.4mm pitch. The SOT-143 footprint is common and well-supported in assembly houses. No exotic handling required — this is a straightforward reflow-solder part.
Lifecycle and sourcing posture
There is no end-of-life notice, no last-time-buy window, and no forced migration risk for new designs. ROHS3 compliant per the manufacturer's declaration. Because the part is active, lead times typically track with standard semiconductor supply — no special broker sourcing required, but the independent channel gives flexibility for urgent or non-standard quantity requests.
