This integrated window monitoring circuit offers robust protection by tracking undervoltage and overvoltage levels with 1 percent accuracy, enabling designers to accelerate system-wide functional safety by providing advanced diagnostic and reset capabilities. The MAX16137 also reduces the solution size by half and helps minimize design complexity.
Functional safety standards drive design direction in the automotive space. Voltage monitors play a critical role in reporting the status of power supplies. Furthermore, these systems must include test circuitry to ensure reliable operation. The MAX16137 offers both on-chip diagnostics and BIST (Building Information System) to help designers more quickly achieve system-wide functional safety for ADAS (Advanced Driver Assistance Systems) and other autonomous driving applications.
The MAX16137's BIST functions verify the supervisor's functionality without requiring external circuitry, reducing design complexity. In doing so, the MAX16137 also reduces the solution size by 50 percent compared to the closest competitor's solution. The supervisor IC can be designed into a wide variety of automotive systems, including infotainment systems, body electronics, powertrains, electric vehicle powertrains, and IoT systems.
