The LM3724IM5-2.32/NOPB is a power management integrated circuit (PMIC) Supervisor, which integrates several functions needed for sophisticated management and supervision of power supply designs. It monitors power supply rails for undervoltage conditions, provides fault diagnostics, and holds the supply rail in a reset condition until the system is properly powered. This advanced supervisor, which contains an integrated voltage regulator, allows designers to simplify their power supply designs, reduce parts count and total cost.

The LM3724IM5-2.32/NOPB is designed to monitor two separate supply rails and each rail can be independently programmed for undervoltage and overvoltage conditions. The two power supply rails, VCCA and VCCB, both have adjustable thresholds of 2.25V, as well as hysteresis of 0.8V to tolerate supply fluctuations. An internal voltage regulator is provided to power the logic from one of the monitored power supplies. This allows the same device to be used in multiple power supply sequencing applications.

The fast response of the LM3724IM5-2.32/NOPB, along with its two independently adjustable thresholds, makes it suitable for many applications requiring tight fault protection and circuit integrity at power-on and power-down, including protection of programs stored in memories or devices. An open drain active low reset output is available to ensure all devices or memories are properly reset.

Also, the LM3724IM5-2.32/NOPB has extended operating temperature range, up to +125°C, making it ideal for use in extreme environments, such as automotive and aerospace applications. The device also has extended supply voltage range of 3V to 15V, which allows the designer to use a wide variety of existing supplies and system configurations.

Another key feature of the LM3724IM5-2.32/NOPB is the ability to monitor both power supplies simultaneously. The device can monitor the two independent power supplies and will detect if one fails, allowing for fast response time and better protection for critical components. It also provides diagnostics for failures, allowing for easy troubleshooting.

The LM3724IM5-2.32/NOPB is an advanced power management IC Supervisor suitable for many different power supply applications. Its flexible design, extended temperature range, and adjustable monitoring thresholds make it a valuable addition to many power supply designs. Its simultaneous monitoring capability helps protect critical systems and components, while its extended operating temperature range allows it to be used in extreme operating environments.
