What the 4.65V threshold means for your 5V rail
That threshold is set for a typical 5V ±10% system — it catches brownouts before the logic rails collapse, but it won't trip on normal ripple. The reset stays asserted for a minimum of 160ms after the rail recovers, which gives the oscillator and PLL time to stabilize before the processor starts executing. This is the kind of part you drop into a 5V microcontroller or DSP design where you need a clean, glitch-free boot sequence without a lot of extra circuitry.
Active High and Active Low — one part, both polarities
Both Active High and Active Low reset outputs are available from this single device, so you can drive a processor that expects a logic-high reset and a peripheral that expects a logic-low reset from the same supervisor. That saves a resistor divider or an inverter on the board, which matters when you're packing a tight layout or trying to keep the BOM count down.
Package and field-swap reality
It comes in an 8-SOIC package with a 3.90mm body width — a standard footprint that any technician can hand-solder with a fine-tip iron. No hot-air station needed, no QFN pads to inspect under a microscope. If you're carrying a field kit, this is the kind of part you can swap on site without a lab bench. The Tape & Reel suffix (REEL) means it ships on a reel for automated pick-and-place, but it's also available in Cut Tape for prototype or repair quantities.
It won't handle under-hood automotive or downhole drilling temperatures, but for the vast majority of 5V-supervised designs in conditioned or semi-conditioned environments, this is the right temperature grade.
Lifecycle and sourcing posture
It is ROHS3 compliant. If you need a volume commitment or a scheduled release, let us know when you send the RFQ.
