Voltage monitoring IC saves space, offers self-test feature
Maxim Integrated has developed a window voltage monitor with integrated self-test for its Essential Analogue product range. Target applications are found in the field of driver assistance systems

Designers working on the functional safety of automotive Advanced Driver Assistance Systems (ADAS) can reduce the size and complexity of the solution with Maxim Integrated's MAX16137 single-channel Supervisor with Built-in Self-Test (BIST). The device monitors under- and over-voltages with 1% accuracy and enables functional safety to be ensured through advanced diagnostics and reset functions. The chip also halves circuit size and helps simplify design.

The MAX16137 offers both diagnostic and BIST functions at the chip level. As such, it helps developers achieve system-based and functional safety for ADAS and other autonomous driving applications faster. The device's BIST functions verify supervisor functionality without the need for external circuitry, reducing design complexity. In this way, the chip also reduces circuit size by 50% compared to the nearest competitor solution. The supervisor IC can be used in a wide range of automotive systems such as infotainment, body electronics, power, electric vehicle powertrain and IoT systems.

The MAX16137 provides precise voltage monitoring (under- and over-voltage) with ±1% accuracy. The threshold can be factory set from ±4 % to ±11 % of the target voltage. An evaluation kit is available to get you started with the MAX16137.
