The BD4828G-TR product family is a class of power management Integrated Circuits (PMIC-Supervisors) marketed by the Rohm semiconductor company. These specialist devices are used by the electronics design community in a variety of low power, low voltage applications to monitor battery voltages, power output and status, among other related functions. This article looks in detail at its primary application field, as well as the underlying working principles.

The BD4828G-TR is suitable for a number of applications in the field of battery management and monitoring. Applications include monitoring the charge of lithium ion, nickel cadmium and nickel metal hydride cells, as well as their associated battery voltages. Other specialist applications include the monitoring of 4.2V systems and battery over-discharge protection, thermal runaway protection and other power output safety measures.

The device itself is fabricated in a compact 8-Lead DFN (exposed pad) package. It utilizes a voltage supervisor topology in order to accurately monitor and protect battery voltages, and is capable of precision monitoring from as little as 2.5 volts up to 4.5 volts. The device is designed to work with standard cell phone batteries as well as other popular sizes, making it an ideal choice for a variety of applications.

The BD4828G-TR employs a voltage supervisor topology in order to monitor and protect battery voltages. This is achieved using two primary elements, a voltage reference and a comparator circuit. The reference circuit constrains the monitored output voltage to a predetermined value (within the device\'s operational range) while the comparator compares the monitored voltage to the pre-defined value. If the monitored voltage is outside the stipulated range, then the comparator output is latched and an alert is triggered indicating that the watched voltage is either too high or low outside the allowable threshold.

The device is capable of precision monitoring from as little as 2.5 volts up to 4.5 volts. It is also designed to incorporate a number of safety measures, including thermal runaway protection, battery over-discharge protection, current sensing and monitoring and input/output power output protection. Furthermore, the BD4288G-TR is equipped with integrated direct select pins to control the input/output power output.

Other desirable features of the device include a low power consumption (for extended battery life), a wide operating temperature range (-20C to +85C) and a wide variety of programmable thresholds. This makes the device ideal for use in portable applications where battery life and low power consumption are of key concern. Furthermore, the device is available in a variety of formats and can be used with a number of different connectors to accommodate a wide range of applications.

The Rohm BD4828G-TR is an ideal choice for applications requiring accurate and reliable monitoring of battery voltages and/or power output. Its relatively small form factor, wide variety of features and extended temperature range make it an attractive option for portable device applications where battery life and low power consumption are of paramount importance.
