BD45285G-TR Integrated Circuits (ICs)

The BD45285G-TR is a supervisor circuit designed for the protection of circuits by monitoring a variety of supply voltages. Supervisors are a type of power management integrated circuit (PMIC) and are used to detect harmful conditions, such as overvoltage or overcurrent, as well as conditions that may prevent the circuit from operating correctly, such as undervoltage. They can also be used to detect more complex conditions, such as a brown-out or power-on reset (POR). The BD45285G-TR is a multi-functional supervisor with a variety of protection and reset modes that can be used for a wide range of applications.

The BD45285G-TR is primarily designed for use in automotive and industrial applications, where reliable power is essential to ensure the integrity of the system. It is also suitable for consumer electronics, such as home appliances, phones, laptops, and portable devices. The BD45285G-TR can be used to protect circuits against overvoltage, undervoltage, overcurrent, brown-out and power-on reset events.

The BD45285G-TR can be used to monitor a variety of power supply voltages, from 4.5V to 3.3V. It can also detect a variety of conditions, such as low voltage or overcurrent. When an unsafe condition is detected, the BD45285G-TR will generate a reset signal to reset the device. The duration of the reset is adjustable, allowing for more precise control over the reset event. The reset can also be triggered manually.

The BD45285G-TR includes multiple protection and reset modes, such as overvoltage, reset enable, and manual reset. The overvoltage protection mode triggers a reset if the voltage exceeds a certain threshold set by a voltage divider. The reset enable mode provides a way to manually enable or disable the reset output. This mode can be used to prevent unwanted resets during power-up or power-down. The manual reset mode allows for the reset output to be triggered manually, by a external signal.

The BD45285G-TR also provides a voltage monitor output which can be used to detect a low voltage condition. This output can be used to control logic circuits or to provide additional protection against a brown-out event. The output can be programmed to generate a reset when the voltage falls below a certain threshold.

In summary, the BD45285G-TR is a versatile supervisory circuit that can be used for a variety of power monitoring and reset functions. It can be used in automotive and industrial applications, as well as consumer electronics. It provides overvoltage, undervoltage, overcurrent, power-on reset, and manual reset protection, as well as a low-voltage monitor output. The reset duration is adjustable and reset can be triggered manually or by an external signal.
