Maxim introduced the industry's first automotive-grade window voltage monitor with a self-check function, ideal for advanced driving assistance systems

MAX16137 helps automotive system engineers achieve functional safety goals, reducing the size of the solution by 50%.

Beijing, ChinaJune 16, 2021Maxim Integrated Products, Inc. (NASDAQ: MXIM) announced the launch of the MAX16137 single-channel window voltage monitor with built-in self-test (BIST) function to help with advanced driving assistance systems (ADAS) ) Design engineers achieve functional safety goals, reduce design complexity and reduce program size. This window voltage monitoring IC can track Undervoltage and overvoltage levels with an accuracy of up to 1%, thereby providing highly reliable protection; advanced diagnostics and reset functions help engineers accelerate system-level functional safety design. In addition, the use of MAX16137 can reduce the size of the program by half, which helps reduce design complexity.

Functional safety standards promote the design direction in the automotive field. The voltage monitor is essential for reporting the health of the power supply. In addition, these systems must include test circuits to ensure reliable operation. MAX16137 provides diagnostic functions and chip-level BIST to help designers quickly implement system-level functional safety design, suitable for ADAS and other autonomous driving applications.

The BIST circuit of the MAX16137 is used to check the functionality of the monitoring circuit without the need for external circuits, thereby reducing design complexity. Accordingly, the MAX16137 has a size reduction of 50% compared to the closest competing solution. This monitoring circuit IC can be designed for various automotive systems, such as infotainment systems, body electronics, power supplies, electric vehicle power systems, and IoT systems.

Maxim's basic analog IC integrates advanced low-power, high-performance, single-function products, suitable for various application fields, and provides a guarantee for the innovation of next-generation products.

Main advantage

Built-in self-checking function: The chip-level advanced diagnostic function helps developers to meet the system-level functional safety requirements with a smaller circuit board area.

·High-precision window voltage monitoring: Undervoltage/overvoltage (UV/OV) voltage monitoring accuracy is as high as ±1%, which can be set by the factory to ±4% to ±11% of the target voltage.

·Small size: No need for external diagnosis and test circuits, and the size of the solution is reduced by 50%.

·Simple design: reduce the complexity of system development.

Evaluation
