BD46455G-TR Application Field and Working Principle

The BD46455G-TR is an ultra-low power pulse width modulator (PWM) controller with integrated Brown-Out Detect (BOD) and power on reset (POR) functions. It is designed to simplify power supply design and improve efficiency of low-power applications. The device offers a wide range of features, including minimal operating current, a wide range of integrated features, programmable output current limit, adjustable Brown-Out Detect (BOD) voltage threshold, and automatic power-on reset. The low battery detect (LBD) is monitored using a digital logic signal from the PIC microcontroller, which can be set to detect a low battery voltage event or detect a slight decrease in voltage.

The BD46455G-TR is capable of providing a precise and stable pulse width modulation (PWM) control for low power applications such as portable electronic devices, automotive applications, and computer peripherals. It can also be used to provide precise, synchronized and accurate power conversion for battery management and other applications. With its integrated Brown-Out Detect (BOD) and Power On Reset (POR) features, it ensures safe shutdown and uninterrupted operation of power system under fault conditions. The device has adjustable parameters such as low battery threshold and BOD delay time to enable further optimization of performance, making it suitable for a wide range of applications.
