Power management integrated circuits (PMICs) are used to regulate and manage different power sources for a wide range of applications. One of the most important uses for PMICs is battery management, which involves managing the performance of batteries and other energy storage devices. The BQ7693001DBTR is a power management integrated circuit (PMIC) specifically designed for battery management applications. This application note describes the application field and working principle of the BQ7693001DBTR.

The BQ7693001DBTR is a PMIC specifically designed for battery management applications. It is a three-channel power management IC, providing three independent power channels for the management of three independent Li-ion batteries. The BQ7693001DBTR allows for current sensing, voltage sensing, and temperature monitoring of all three Li-ion batteries. It also provides a safety shutoff in the event of over-charge and over-discharge of any of the three batteries.

The BQ7693001DBTR is designed for use in a wide range of battery-powered devices, from consumer electronics to electric vehicles. It is ideal for applications where multiple Li-ion batteries need to be managed and monitored. These applications can range from cell phones and tablets, to power tools, to electric vehicles and boats.

The BQ7693001DBTR features three independent power channels for Li-ion battery control and management. Each power channel is capable of monitoring and regulating the voltage, current, and temperature of the corresponding Li-ion battery. The BQ7693001DBTR also features a safety shutoff mechanism to protect against over-charge and over-discharge of the batteries. It supports automatic battery disabling in the event of voltage exceeding the OVP threshold, or current exceeding the OCP threshold, as well as temperature monitoring of the batteries.

The BQ7693001DBTR utilizes a voltage-mode control with externally adjustable current sensing and voltage sensing. The power switch is controlled by an adjustable fixed-frequency, maximum-duty-cycle PWM voltage mode controller. The power channels that can deliver output voltages from 2.1V to 5.5V and currents up to 5A. The output voltage can be adjusted via an external reference voltage, and the output current can be adjusted via an external sense resistor.

The BQ7693001DBTR features built-in safety features for protection against over-voltage, over-current, and over-temperature conditions. The over-voltage protection (OVP) and over-current protection (OCP) are adjustable and the device also features thermal shutoff protection. The device supports battery pack configuration of up to 10 cells, and it also includes extensive diagnostic and communication features. The device has an SPI interface and a host of other diagnostic outputs including programmable interrupt and power-on reset.

The BQ7693001DBTR is a robust and reliable PMIC for battery management applications. It features adjustable over-voltage, over-current and over-temperature protection as well as programmable current sensing and voltage sensing. The device can monitor and regulate the voltage, current and temperature of all three Li-ion batteries, providing a reliable and safe means of managing multiple Li-ion batteries. With its extensive diagnostic and communication features, the BQ7693001DBTR is an ideal choice for battery management in a wide range of applications.
