The BD87A29FVM-TR is a cost-effective supervisory circuit with four independent voltage detectors and reset outputs which are ideal for microprocessor-based systems. This multi-functional supervisory circuit monitors its four power supplies, resetting the system when power supply conditions exceed pre-programmed thresholds. It has a built-in temperature monitor and reset delay circuit capable of delaying the reset signal for up to 1.5 seconds.

The primary application field of the BD87A29FVM-TR is for system monitoring and power on reset for microprocessor-based systems. It is also used for preventing bus unlock and reset/stop outputs. It can also help to make system power supply design more efficient through large-scale integration. The BD87A29FVM-TR is a flexible, high-capacity supervising IC, making it ideal for use in many applications.

The BD87A29FVM-TR works mainly by comparing its input voltage to a voltage reference. When the voltage reaches the set protection level,the reset is automatically generated. This reset signal is then sent to the system controller/processor. The reset delay circuit provides an adjustable delay time to ensure that the system reset is successful and accurate. This delay time can range from 0.05 to 1.5 sec. The BD87A29FVM-TR also has an internal threshold comparator that monitors the temperature of the application. When the temperature exceeds the preset level, the reset signal is triggered.

The BD87A29FVM-TR also has five input pins for two external reset signals, a step-down voltage detector, and two other signals. These two other signals can be used for various functions depending on the system requirements. For example, they can be used as an on/off switch, an enable signal for the reset, or a signal for a low battery detection. The two external reset signals allow for an additional level of system protection. These two signals can be also used for monitoring extra supply voltages in the system.

The BD87A29FVM-TR is ideal for use in any microprocessor-based system that needs a supervisory circuit with adjustable delay and temperature monitoring. Its low cost and high degree of integration make it an ideal choice for a wide range of applications. Additionally, its easy-to-use features, such as the voltage and temperature monitor and reset circuitry, provide additional protection for your application and provide peace of mind.
