What are the key features of MAX16126TCB+?
- Adjustable overvoltage threshold via external resistor divider enables protection tuning for 12 V, 24 V, or 48 V automotive supply rails
- Load-dump protection guards electronics against ISO 7637 automotive transient spikes exceeding 40 V on vehicle power lines
- Reverse-battery protection prevents damage from negative voltage conditions by controlling an external pass FET
- Compact 12-pin LFCSP 3×3 mm package minimizes board area in space-constrained automotive ECU and industrial designs
What is MAX16126TCB+ used for?
The MAX16126TCB+ is designed for automotive ECUs, telematics modules, and vehicle body electronics where load-dump transients and reverse-battery events on 12 V or 24 V rails can damage unprotected circuits. It controls an external power FET to rapidly disconnect the load when input voltage exceeds the adjustable threshold or reverses polarity, protecting downstream regulators, microcontrollers, and sensors from ISO 7637 automotive transients. The compact 12-pin LFCSP package supports high-density automotive PCB layouts in infotainment systems, ADAS modules, and industrial motor controllers.
