Power Management Integrated Circuit (PMIC), an integrated circuit that helps manage power supply, is an important part of any electrical system. PMICs are usually divided into three categories - voltage regulators, voltage supervisors and supervisors. As part of the supervisor category, the TPS3836E18DBVR is a precision low-power voltage supervisor designed to support and protect a variety of electronic systems in a variety of conditions. Providing long-term protection and reliability with precision monitoring, the TPS3836E18DBVR is essential for applications in consumer electronics, automotive, industrial, and medical systems.

Application Field

The TPS3836E18DBVR helps ensure that the operating conditions and voltages in the system are in a safe range. It can regulate the system\'s shut-down and reset logic signals, ensuring that the system\'s voltage regulator and other system components are operated within the required specifications. As a supervisor, TPS3836E18DBVR can be used in a wide range of applications, mainly in consumer electronics, automotive, industrial, and medical systems.

• Consumer Electronics: TPS3836E18DBVR provides accurate monitoring of CPU performance and temperature in order to maintain system stability and correct operation.
• Automotive: It enables the system to recognize voltage problems and activates a reset pulse in time to prevent system lock-up.
• Industrial: It monitors power-on reset/sequencing/monitoring in a rugged industrial system.
• Medical: It can be used in medical system to ensure patient safety.

Working Principle

The TPS3836E18DBVR integrated circuit (IC) is a low voltage supervisor that monitors a high-accuracy voltage detector and supports a variety of reset and shut-down logic signals. The chip is specially designed to operate in a wide range of environmental conditions, from -40°C to +125°C, making it suitable for use in harsh environments. The IC has an internal high-accuracy voltage detector with a default 0.25% accuracy (when measured at ambient temperature). The voltage detector typically monitors the system\'s supply voltage levels and sends out reset/shutdown logic signals if they are out of the normal range.

The device also features a proprietary "Instant-on" threading pulse, which allows for a fast response to power supply changes without waiting for the reset/shut-down logic signals to start the reset/shut-down process. The device is powered on using a selectable logic threshold, allowing the designer to select from multiple outputs, including reset and shutdown logic signals. In addition, the IC is equipped with an Error Output pin, which offers an early warning sign of any faults.

The user can configure the TPS3836E18DBVR to their needs by adjusting several parameters like threshold accuracy, hysteresis, pullup and pulldown resistance, polarity and various other features like brownout or disable modes. The IC also features an optional acknowledge feature, which allows the user to determine if the IC has been properly configured. The TPS3836E18DBVR has a very low power consumption, so it can be used in battery-powered applications with confidence.

Conclusion

The TPS3836E18DBVR is an essential integrated circuit for a variety of applications, ranging from consumer electronics to medical. Its high-accuracy voltage detector and associated reset/shutdown logic signals ensure that the system is always operating properly, giving design engineers peace of mind. By taking advantage of its Instant-on threading pulse, it offers reliability and performance in a wide range of environments, making it an excellent choice for all types of applications.
