The BD4932G-TR is a versatile power management IC (PMIC) supervisor for various embedded systems and microcontrollers, provided by ROHM. It combines various functions of chip reset, power-on reset, reset input detection, and power-on reset output. These features are optimised for the safety of embedded systems and microcontrollers, making this PMIC supervisor an ideal choice for a wide range of applications.

The main features of the BD4932G-TR are its ability to detect a wide range of reset sources and provide a reset signal in response. It offers three reset input sources, which include a low voltage detection (LVD) pin, a power-on reset (POR) pin, and a reset input pin. In addition, it offers a power-on reset output, which can be customised for different application requirements. The BD4932G-TR also includes a flexible timer, which can be configured to provide a delay between the reset signal and the response signal.

The BD4932G-TR is suitable for a range of applications, such as consumer appliances, microcontroller-based systems, and industrial applications. It can be used to provide reset signals for microcontrollers and embedded systems, ensuring reliable operation in the event of a range of reset sources, including power on reset, low voltage detection, and reset input.

The operation of the BD4932G-TR is based on an internal voltage supply. This provides power to the reset input, the LVD, and the POR pins. When any of these is triggered, the internal voltage drops, causing the reset signal to be outputted. This reset signal is then used to reset the device or microcontroller. The reset time and delay are adjustable, allowing for a customised fit of the reset output to the application.

The BD4932G-TR is a versatile solution for reliable reset and power-on reset applications. Its three reset input sources, adjustable timer, and power-on reset output make it an ideal choice for a range of embedded system applications. With its small size and easy to use interface, the BD4932G-TR is a convenient and reliable choice for low power applications.
