AP2820EM-G1

The AP2820EM-G1 is a power management integrated circuit (PMIC) that belongs to the family of power distribution switches, load drivers, and LED drivers. Its main function is to control power supply, application of the device depends on its output current, requested outputs, and environment temperature. To maximize its efficiency, the AP2820EM-G1 has two power channels with four power domains - one dedicated for load/LED/CPU. On-chip precision regulators ensure low power dissipation and low system noise.The AP2820EM-G1 core operates with an adjustable output power-supply voltage that is maintained at a constant level by the on-chip linear regulators based on the external power supply. The input voltage range is 1.8-5V, the output voltage range is 1.20-3.3V, and typical load current is 1A. Output voltage for each channel can be individually adjusted.

The AP2820EM-G1 has various protection features to protect from short circuit, over-voltage, over-current, thermal, and other circumstances. Its current limit mechanism enables the device to precisely limit the output current within the set range. It has an adjustable power-on time, with the help of which user can set the start time of the output power. The device also has sleep mode power-off functionality, it automatically powers off the device when it is not in use. It also has a software shutoff facility which on activation will shut off the device.

The AP2820EM-G1 is available in a Molded-Lit single-row packages and is ideal for applications such as wearables, smartphones, tablet PCs, vending machines, and other equipment dealing with low-power wearables. It also provides improved system performance and increased thermal efficiency, robust surge protection, over-voltage and over-current protection, and load current monitoring in the smaller board area.

In conclusion,AP2820EM-G1 is a highly integrated power management IC (PMIC) that is ideally suited for applications such as wearables, smartphones, and tablets, providing improved system performance, increased thermal efficiency, and robust surge protection, over-voltage, and over-current protection. It has power channels with four power domains and its input voltage ranges from 1.8-5V with an output voltage of 1.20-3.3V. It has on-chip precision regulators to ensure low power dissipation and low system noise. And different protections such as short-circuit protection, over voltage protection and over current protection.
