PMIC, or power management integrated circuits, are widely used in advanced electronic systems. Battery management is a critical area of PMIC design which requires precise system control over voltage, current and temperature. The BQ4050RSMR is a state-of-the-art PMIC for battery management applications. It was developed by Texas Instruments (TI) with features that provide superior system performance, flexibility and reliability. This article provides an overview of the BQ4050RSMR application field and working principle.

The BQ4050RSMR is designed for battery management in various applications like wearables, IoT, telecommunications, energy storage systems and automotive. The BQ4050RSMR offers Flexible 2-Cell Li-Ion/ Li-Po Battery Management, as well as high performance voltage charging control and a robust system control. This device is capable of supporting up to 6 series cells to attain a wide range of battery capacity and voltage. The BQ4050RSMR has integrated boost and buck regulation, as well as protections such as short circuit, overcurrent and overvoltage. Furthermore, the device offers a high level of system flexibility, allowing users to configure the power-up sequence and enable/disable system functions.

The BQ4050RSMR integrates TI\'s Ultra Low Power (ULP) Control Core, a low-power analog and digital control unit. The ULP Control Core features adaptive control that automatically adapts to the load and cycle conditions without any external components or feedback, resulting in high efficiency over a wide range of load and cell conditions. The BQ4050RSMR also features low current consumption for lower system cost and extended battery life. The ULP Control Core supports a wide range of input ranges and hysteretic and non-linear output regulation. This device can manage the charge curve and temperature compensation of multiple cells during the charging process.

The ULP Control Core can operate from battery power or from an external power supply. The BQ4050RSMR supports up to five independent high-voltage system regulators and up to three low-voltage switching and linear regulators. In addition, it has digital comparators that monitor and control the status of the system. The device also has a programmable boost regulator and adjustable charging current and battery voltage limits. The BQ4050RSMR also includes a precision analog battery, system and temperature measurement interface. This allows the device to accurately monitor the battery and system conditions in order to take the appropriate corrective action.

The BQ4050RSMR provides users with access to an integrated system monitoring and protection engine. The System Monitoring and Protection Engine (SMPE) helps protect the system from damage due to overcurrent, overvoltage, overtemperature and short circuit. The device also features one or two channels for system reset, one or two channels for system delay, and two to four channels for system monitoring. The BQ4050RSMR provides an integrated programmable low-voltage reset and low-voltage monitoring. The device also has a flexible I2C interface for communication with other system components and for accessing system information.

The BQ4050RSMR offers an excellent combination of features that provide superior performance, flexibility, and reliability. The ULP Control Core and integrated System Monitoring and Protection Engine ensure that the system is kept in a safe operating condition. The flexible input, output and feedback configurations provide users with flexibility in designing systems that meet their specific requirements. The integrated temperature compensation and system monitoring provide further assurance that the system maintains proper operation.
