XC6121D738MR-G Datasheet/PDFPMIC (Power Management Integrated Circuits) are used to efficiently manage and monitor the power systems in a variety of applications, ranging from automotive and industrial to mobile and consumer products. The XC6121D738MR-G is a versatile PMIC that can be used to monitor and manage the power system of single-cell lithium-ion (Li-ion) batteries. It is highly desirable for applications where cost and space are a consideration, such as low-cost handheld devices.The XC6121D738MR-G is an ultra-low-power supervisory IC (Supervisor IC) that is capable of monitoring and supervising the voltage of a single-cell Li-ion battery system. It is specifically designed to provide efficient power management for handheld applications such as digital cameras, cellular phones, and PDAs. It is ideal for applications where space and power saving are important considerations. The XC6121D738MR-G offers a compact and cost-effective solution for these applications.
The XC6121D738MR-G provides a power-on reset (POR) mechanism, which ensures that the system starts up properly by monitoring the voltage level of the single-cell Li-ion battery. The onboard comparator monitors the battery voltage level and generates an active-low reset signal if the battery is below the predetermined voltage threshold. This reset signal is then used to reset the system. The device also provides an open-drain comparator output (COMP) signal that can be used to indicate when the battery voltage is below the predetermined threshold. Additionally, the XC6121D738MR-G features a battery status indicator (STAT) that is pulled high when the battery is below its predetermined voltage threshold.
The XC6121D738MR-G also provides an over-discharge protection, which prevents the battery from discharging beyond its predetermined limit. The device features an adjustable under-voltage monitoring level that can be set to prevent further draining of the battery’s energy. This ensures that the battery is not excessively discharged, which helps prolong its lifetime. The device also has a timeout feature, which is used to prevent the system from resetting if the voltage level does not exceed a certain threshold for a predefined period of time.
In addition, the XC6121D738MR-G offers a low-current sleep mode, which allows for further power savings. This mode reduces the device’s operating current to only 500nA when the system is in an inactive state. The device can be woken up from this sleep mode using the system’s general-purpose I/O (GPIO).
The XC6121D738MR-G is an ideal solution for applications where space and cost-efficiency are important considerations. With its integrated voltage monitoring and protection capabilities, it can be used to monitor and manage the power system of a single-cell Li-ion battery system. The onboard comparator, reset signal, and battery status indicators are used to ensure that the system starts up properly, and the over-discharge and sleep modes are used for further power savings. This makes the XC6121D738MR-G an ideal choice for a variety of applications such as digital cameras, cellular phones, and PDAs.
