Product details

Load dump and reverse-voltage protector for 12V/24V rails

The Maxim Integrated MAX16126TCB+T is a load dump and reverse-voltage protection IC designed to clamp overvoltage transients and block reverse battery connections on automotive and industrial power rails. It operates from a 3V to 30V supply range, drawing just 224µA quiescent current, and is rated for -40°C to 125°C — suitable for under-hood and outdoor environments. The device comes in a 12-TQFN (3x3 mm) exposed-pad package for surface-mount assembly.

Supply range and protection threshold

With a 3V to 30V supply range, the MAX16126TCB+T covers both 12V and 24V nominal systems plus the headroom needed for load-dump events that can spike above 30V. The 224µA supply current is low enough for always-on protection circuits without draining the battery during key-off periods.

Frequently asked questions

What is the typical application circuit for MAX16126TCB+T?

The device is used as a load dump and reverse-voltage protector placed between the input power connector and the downstream regulator or load. It clamps overvoltage spikes and blocks reverse battery connections without a series diode, saving forward-drop losses.
