What the 3 V threshold and 100 ms timeout buy you
The MAX16161NDK300+: The active-low, open-drain output pulls low on fault and floats on power-good, so it wire-ORs with other supervisors on the same reset line without contention. Reset timeout is 100 ms typical — long enough for the main regulator to settle and the oscillator to stabilise before the processor starts executing code.
Housed in a 4-bump WLP measuring 1.06 x 0.73 mm (4-WLP), the MAX16161NDK300+ fits in sensor modules and wearable PCBs where board real estate is the binding constraint. Rated for junction temperature from -40 to 125 °C, it handles under-hood automotive and industrial enclosure ambient without derating the supervisor function.
ROHS3 compliant — no exemption expiry to manage in the supply chain.
