The MIC6315-26D3UY-TR is a Power Management Integrated Circuit (PMIC) from Microchip that is a member of the Supervisors product family. It is intended for non-safety-critical applications, such as battery-powered portable devices or microcontroller-based systems. The MIC6315-26D3UY-TR is designed to provide a robust power management supervision and control solution for single-cell Li-ion/Li-polymer batteries and other power sources, while utilizing minimal component count and board space.

The MIC6315-26D3UY-TR can monitor the battery voltage and provide accurate battery-level information to the system. The switchover threshold voltage is adjustable across a wide range of voltages, improving the efficiency of power management systems. The output can be used to switch between different power supply sources, as well as to control the charging of the battery. The device also includes a power-good (PG) output signal, indicating when the monitored voltage is within an operating range.

Apart from battery monitoring and control, the MIC6315-26D3UY-TR includes multiple features that improve the reliability of power management systems. There is an active discharge feature which allows the user to choose an optimal discharge circuit for their application, improving the overall system efficiency. The device also provides a low battery reset (LBR) output which can be used to reset the system when the battery voltage reaches a certain threshold. Finally, the device has an over-temperature protection (OTP) feature which protects the device from thermal overload. All these features make the MIC6315-26D3UY-TR an excellent choice for portable device designers.

The working principle of the MIC6315-26D3UY-TR is straightforward. It contains an adjustable monitoring circuit that is connected to the battery voltage (VBT) and system voltage (VIN). The monitored voltage is compared with a programmable threshold voltage (VVC). When the monitored voltage reaches or exceeds the threshold voltage, the device triggers the corresponding outputs (LBR, PG, or DIS) and can optionally charge the battery. The IC can also be configured to generate reset signals or interrupt the system when a specific condition is detected.

The MIC6315-26D3UY-TR is an ideal choice for monitoring and controlling a single-cell Li-ion/Li-polymer battery or any other power supply in non-safety-critical applications. Its low component count and simple programming make it an attractive solution for designers of portable devices. Additionally, the power management features such as active discharge, low battery reset, and over-temperature protection make the MIC6315-26D3UY-TR a reliable and efficient choice for reliable, low-power system operation.
