Power management integrated circuits (PMICs) are an essential part of the electronic system, providing several highly-integrated and flexible solutions to reduce power consumption and increase energy efficiency. Supervisory circuits play an important role in the implementation of intelligent power management solutions and exist in large variety of PMIC products. The X40415V8I-BT1 is a surface mount, lead-free, multichannel power supervisor with a safety system compliant to ATAL 1.2.

The X40415V8I-BT1 is intended for use in a variety of markets, including industrial, medical, and information technology application. It is suitable for a wide range of applications, such as communications, consumer electronics, automotive, and renewable energy systems. The X40415V8I-BT1 enables system levels engineers to provide sophisticated power management solutions with its advanced features, such as adjustable asserting and drooping delay time, watch-dog timeout, and low-power operation.

The X40415V8I-BT1 provides a multichannel power supervisor solution with 7 independent (general purpose) and 5 internally multiplexed POK (power-on-key) outputs. Each of the 7 channels provides individually adjustable voltage monitor circuits, with configurable output assertion delay and drooping delay. The 5 internally muxed POK outputs are powered from a single voltage input. Additionally, these outputs also feature adjustable asserting and drooping delay.

The X40415V8I-BT1 also incorporates a unique system-level safety protection, providing confidence that the device does not fail in extreme conditions, such as over-current, under-voltage, and over-temperature. These system-level safety features enhance product reliability and reduce the risk of system failure.

The X40415V8I-BT1 is designed to operate over a wide range of voltage levels, from 1.8V to 5.5V. This allows the supervisor to be used in both conventional and battery-powered systems. The X40415V8I-BT1 can also operate over a wide range of temperatures, from -40°C to +85°C. This extended temperature range makes the supervisor suitable for both normal and harsh environmental application.

In order to ensure a safe and efficient operation, the X40415V8I-BT1 incorporates several features, such as an adjustable Droop interval, an adjustable Assert interval, and an adjustable WDT (Watch Dog Time-out). The Droop interval is designed to detect an under-voltage condition and immediately warn the system, while the Assert interval is designed to detect an over-voltage condition and warn the system. Lastly, the WDT is designed to reset the system in case of a system-level failure.

In addition to providing power supervision, the X40415V8I-BT1 also incorporates several power management features. These include a power-saving mode, an auto-shutdown mode, and a programmable power sequencing. The power-saving mode is designed to reduce power consumption by automatically disabling unused channels, while the auto-shutdown mode controls the supply voltage and reduces power consumption when the system is in a low-power state. Finally, the programmable power sequencing ensures that all connected devices are enabled and disabled in the correct order, according to the power operating conditions.

To summarize, the X40415V8I-BT1 is a surface mount multichannel power supervisor with a safety system compliant to ATAL 1.2. This supervisor provides a sophisticated power solution for a wide range of applications, such as communications, consumer electronics, medical, and information technology applications. It also incorporates several power management features, such as adjustable asserting and drooping delay, watch-dog timeout, and low-power operation. Finally, the X40415V8I-BT1 is designed to operate over a wide range of voltage levels and temperatures, making it an ideal choice for both normal and extreme environmental applications.
