The M40SZ100WMQ6E chip is an active low voltage supervisor with support for PMIC (power management integrated circuit) applications. It is used to detect low supply voltage conditions so the host SoC circuitry can be shut down. The M40SZ100WMQ6E supervisor has two operating voltage ranges, 2.6 V to 3.9 V and 3.0 V to 3.6 V, depending on how the VR1/VR2 pins are set. The chip features an internal 3.2 V voltage reference, along with an external reference connector for connection to external voltage references.

The chip supports the supervisory open-drain output (RESET) which can be used to reset the host SoC. It has a drop-out voltage of 200 mV typical and 0.6 V maximum. The drop-out voltage is the difference between the device\'s regulated output voltage and input voltage before the regulated output is no longer assured. This allows the host SoC to voltage off transition safely.

The M40SZ100WMQ6E also supports an active high-performance supply-voltage monitor output dedicated to 3.2V monitoring. It features a fast voltage monitor response time of 310 μs typically, and 400 μs maximum for microcontroller-based systems.

The M40SZ100WMQ6E is designed to reduce power consumption, enabling longer battery life and less heating from the system. This is achieved through the chip\'s flexible power-down mode control, pre-determined voltage thresholds on the comparative monitor, and adjustable active current levels. Additionally, the voltage supervisor provides dual reset outputs and active reset outputs, different masters/slaves, master/slave push-pull, pull-low/pull-high, blinking reset and power-saving options.

The chip also supports a wide operating temperature range of -55 °C to +130 °C. It is AEC-Q100 Grade 2 certified, guaranteeing reliability and performance in harsh conditions. This makes it suitable for applications requiring low voltage operation, such as automotive, industrial, consumer, and embedded computing.

In summary, the M40SZ100WMQ6E supervisor offers low operating voltage, fast response time and a wide operating temperature range. Its flexible power-down mode control, pre-determined voltage thresholds and adjustable active current levels allow for efficient power management to support long battery life and low heating. Its AEC-Q100 certification further guarantees reliability and performance in harsh conditions, making it an ideal solution for automotive, industrial, consumer and embedded computing. applications.
