Product details

What the wide input range and low quiescent current mean for the BOM

The 3V to 30V supply range means this single IC can serve 12V passenger-car, 24V truck, and 28V aerospace nominal rails without a separate pre-regulator. The 224µA supply current is the standby draw — critical for ECUs that stay powered when the ignition is off, where every microamp competes against the battery-drain budget. At 125°C ambient the part still holds its protection thresholds, so no derating curve worry for engine-bay placement.

It is ROHS3 compliant.

Frequently asked questions

Is MAX16126TCA/V+ AEC-Q100 qualified?

Yes, the MAX16126TCA/V+ is listed under the Automotive, AEC-Q100 series, confirming qualification to the AEC-Q100 stress-test standard for automotive-grade ICs.

What is the difference between MAX16126 and MAX16127?

Both are load-dump/reverse-voltage protectors in the same family. The MAX16126 includes an integrated overvoltage comparator with an adjustable threshold; the MAX16127 uses a fixed 27V clamp. For the MAX16126TCA/V+, the threshold is set by an external resistor divider, giving flexibility to tailor the trip point to the downstream converter's absolute maximum rating.

Can MAX16126TCA/V+ protect against reverse battery?

Yes, the part is described as a load-dump and reverse-voltage protection IC. It blocks reverse-polarity connections on the input rail, preventing damage to downstream electronics.

Is MAX16126TCA/V+ compatible with 24V systems?

Yes, the 3V to 30V input range covers 24V nominal systems (typical 28V steady-state, 36V load-dump). The part's 30V maximum supply rating accommodates 24V truck and military vehicle rails.
