The BD45415G-TR is a device from the PMIC - Supervisors family, which is employed for system resetting, generating and protection. It combines reset generation, voltage, temperature and watchdog monitoring on a single chip with a very small footprint. This module has two field programmable inputs and can provide a very flexible response in system management.

Applications

The primary purpose of the BD45415G-TR is to detect voltage, temperature and watchdog faults, this making it a great tool for any system. This device can be used in various circuits, such as those for industrial and automotive equipment, computer boards, and radio communications systems. It is specially designed for automotive systems and industrial applications where multiple circuits must be managed to provide added safety and reliability. Furthermore, this device can act as a supervisor in a system reset circuit.

Working Principle

The BD45415G-TR is a modular system management device, which can monitor voltage, temperature, and watchdog faults. It is based on an 8-bit microcontroller which has two programmable inputs for setting reset delay levels and thresholds. The device is able to detect VSL monitoring faults and the reset control output is connected to an external circuit. The VSLs, which can be set to monitor power planes and Vout domains, can generate reset signals when their voltage drops below predetermined thresholds.

When the reset function is activated, the device generates an internal reset signal, which is then propagated through to an external reset circuit. The internal reset signal can be used to activate/de-activate power plane switches, as well as reset the system. Furthermore, an internal temperature sensor is also included, which can detect sudden increases in temperature. The temperature sensor can be set at different thresholds, and can cause a reset signal to be triggered once one of these thresholds have been breached.

The BD45415G-TR watchdog function can also be used to detect system malfunctions, or failures. The device provides an internal oscillator which can be used to configure the watchdog timeout period. Once the configured period has elapsed, a reset signal will be generated. This timeout period can also be reset during normal operation.

The BD45415G-TR can also be used for multiple clock signals generation, allowing multiple clocks to be generated from a single source. This reduces system complexity and costs. In addition, this device can also be used to provide supply voltage level control, which can be employed to control the power supply switching and switching frequency of digital circuits.

The flexible software architecture of the BD45415G-TR allows for user-defined settings and behaviors. An on-chip flash memory can be programmed with optional settings, which can be accessed during system operation. This makes it easy to customize the behavior of the module for specific applications.

The BD45415G-TR is a highly advanced system management device, providing voltage, temperature and watchdog monitoring, as well as clock generation and supply voltage control. Its compact size allows it to be mounted on a circuit board, and it is an ideal solution for applications which require system resetting and complex management.
