G2225RV1U In Stock GMT 4+2 Channel PMU Authorized GMT Electronic Components Agent

The G2225RV1U is a power management integrated circuit (PMIC) designed for wearable, sports-cam, and IP-CAM applications. Here is an English introduction for the G2225RV1U:

G2225RV1U – 4+2 Channel PMU for Wearable / Sports-CAM & IP-CAM Application

The G2225RV1U provides a comprehensive power supply solution for wearable and sports cameras, as well as IP cameras. It includes four DC/DC converters, one power switch, and one low quiescent current LDO to power each critical block of the system. This PMIC is optimized for maximum battery life, featuring low ground current during standby mode operation. All channels of the DC/DC converters operate at a selectable frequency of 1.5/3.0MHz to optimize size, cost, and efficiency. The synchronous converters operate in pulse skipping mode at light load, which further enhances efficiency.

Key Features of the G2225RV1U include:
– Input Voltage Operation: 2.8V to 5.5V, ensuring compatibility with a wide range of power sources.
– Efficient DC/DC Converter:Achieves up to 95% efficiency, contributing to the overall power efficiency of the system.
– Built-in Converters:Includes 4-channel synchronous buck converters, 1-channel power switch, and 1-channel low quiescent current LDO for RTC (Real Time Clock). The bucks can be set to lower quiescent current at low load, which is beneficial for power-sensitive applications.
– Low Power Consumption: In sleep mode, the power consumption is less than 20μA, which is ideal for battery-powered devices that require long operation times between charges.
– Switching Frequency: Offers 1.5MHz and 3MHz switching frequencies, allowing for the optimization of size and efficiency in the design of the power supply.
– Power ON/OFF Sequence: Built-in for PMU (Power Management Unit), which helps in managing the power-up and power-down sequences of the system.
– Protection Features:Includes Short Circuit Protection (SCP), Under Voltage Protection (UVP), and cycle-by-cycle current limit for DC/DC converters, ensuring the reliability and safety of the power supply.
– Thermal Shutdown Function:Protects the device from overheating, which can be critical in enclosed spaces or high-power applications.
– VCC OVP Function: Built-in Over Voltage Protection for the VCC line, adding an extra layer of safety to the power management.
– Package: The G2225RV1U is available in a TQFN4x4-28 package, which is compact and suitable for space-constrained applications.

The G2225RV1U is suitable for applications where efficient power management and compact design are crucial, such as in wearable devices, sports cameras, and IP cameras. Its high efficiency and integrated features make it a powerful solution for modern power-sensitive electronics.
