BQ7694002DBTR

Power management integrated circuit (PMIC) products are widely used in the electronic device industry. They are essential components in electrical products which introduce safety, stability and compatibility. Battery management is an important part of PMIC products due to its vital role in the success of any electronic device. The BQ7694002DBTR is an example of a PMIC product offering battery management solutions.

The BQ7694002DBTR is a Dual Battery Transceiver (DBTR) integrated circuit (IC) specifically designed for use with dual battery systems. The device simplifies battery management and communications between two batteries in a system to provide reliable and consistent performance. The device features ultra-low power requirements for superior energy efficiency and is suitable for use in aerospace, consumer electronics, automotive, and medical applications. It is capable of operating over a wide input voltage range from 2.7-28V and its output voltage range is 0.8-25V.

The BQ7694002DBTR features a dual-channel architecture for monitoring and control of each battery independently. The device can simultaneously measure two battery voltage and temperature levels and provide relevant data to an external controller or host processor. The BQ7694002DBTR also features a built-in charge-discharge current detection circuit which can accurately measure the amount of current passing through the system. This feature is essential for monitoring battery power consumption versus charge state and enables system failures to be quickly diagnosed and avoided. Additionally, the device includes an on-board thermistor temperature detection circuit which can be used to detect battery temperature and provide system protection against over-temperature.

The BQ7694002DBTR also incorporates a series of programmable functions to support multiple protection and management operations. It has an adjustable voltage window function which enables the device to detect and indicate when a battery\'s average voltage is out of a user-defined range. It also features adjustable temperature and voltage slip alarm levels which allow the device to automatically initiate alarms if temperature or voltage falls below user-defined thresholds. These features can be used to provide system shut-down protection or to initiate maintenance and diagnostic procedures. The device also features selectable hydrogen sulfide (H2S) detection, allowing the detection of dangerous gases present near the batteries.

The BQ7694002DBTR is a high-performance, low-power device for efficient and effective battery management. It features an advanced architecture which provides reliable and consistent performance in applications where dual battery systems are used. The device supports both analog and digital communications and can be used to provide fast and reliable data transfer between two batteries in order to support more efficient power management in a variety of applications. The device\'s ability to measure voltage and temperature levels, detect current passing through the system, and issue alarms based on user-defined thresholds provide significant advantages over traditional battery management techniques.
