Introduction of TPS65023QRSBRQ1

TPS65023QRSBRQ1, produced by Texas Instruments, is a high frequency, synchronous, 4-or 5-output power management IC. It is considered as a serious contender in power management ICs for its wide range of capabilities. It is a low-cost device and is mostly used for battery management applications.

Application Field of TPS65023QRSBRQ1

TPS65023QRSBRQ1 can be used in various applications where battery management is essential, such as digital cameras, portable devices, and automated demand response systems,The TPS65023QRSBRQ1 provides a complete system for battery management applications, with four outputs for powering the device, battery charger, and voltage regulator, and an additional output for optional low power applications. It also provides an externally programmable adapter recognition feature, enabling the device to recognize various adapters and adjust the power being supplied accordingly.In addition, TPS65023QRSBRQ1 provides many safety features, such as Over-Voltage Protection (OVP) and short-circuit protection (SCP), as well as thermal protection, which helps protect against thermal runaway.Moreover, TPS65023QRSBRQ1 provides a wide input and output voltage range, with a wide input voltage range from 3V to 24V, and output currents up to 2.2A. Furthermore, the device provides a high-efficiency system, and operates in many modes, such as Static (CTRL) and Skin (MODE) control.

Working Principle of TPS65023QRSBRQ1

The working principle of TPS65023QRSBRQ1 is based on a three-phase power conversion technique. In this technique, three voltage-controlled switches (VCS) are connected in series between the input voltage source and the output.The VCSs are connected to each other in the order of: VCS1, VCS2, and VCS3. The output voltage of the TPS65023QRSBRQ1 is determined by two regulated signals, VDD and DISC, which control the on/off state of each VCS, as well as the switching frequency of the device.The VCSs will be turned on and off in a particular sequence to generate a stepped output voltage. This output voltage is processed by the integrated POR circuit and is used to control the charging circuitry of the device. The generated output is adjustable from 0.6V up to 13.3V, depending on the external voltage source and the required output current. Apart from that, the TPS65023QRSBRQ1 also provides a power-up sequence generator and a charge pump, which can be used to provide up to 5.5V output voltage, even when the input voltage is as low as 3V or lower.

Conclusion

TPS65023QRSBRQ1 is suitable for applications where battery management is essential. It is easy to use and has many advanced features, such as Over-Voltage Protection (OVP) and short-circuit protection (SCP), as well as thermal protection. Furthermore, it offers a wide input and output voltage range and high efficiency operating modes. It is especially recommended for those who are looking for an affordable yet reliable alternative for battery management.
