MP62131ES-LF

MP62131ES-LF is a power management integrated circuit (PMIC) containing various power distribution switches, load drivers, and other related circuitry. It provides an economical and efficient solution for managing power consumption in applications with moderate to high power levels. The device includes several integrated power control circuits, including a negative charge pump regulator, low dropout regulator, high side and low side power switches, and a low voltage battery monitoring circuit.

The negative charge pump regulator is an adjustable supply that supplies up to 3 V to the load when the battery voltage drops below a certain threshold. This allows the application to operate in shutdown mode with minimal power consumption. The negative charge pump regulator also protects the system against battery damage due to overcharge or discharge.

The low dropout voltage regulator can provide up to 300 mA continuous at 3.3 V to supply power to the load. It operates with up to 40V input and has improved startup performance, as well as overvoltage, current and temperature protection.

The high side and low side power switches enable the user to quickly switch between multiple power sources. This can be used to operate the application with either the battery or an AC adapter. The power switches also provide a shutdown feature, which can be activated when the battery voltage drops below a certain threshold.

Finally, the MP62131ES-LF features a low voltage battery monitoring circuit. This allows the application to determine the battery level so that it can take corrective action if the battery voltage is low. This can include switching to a backup battery or shutting down the application.

MP62131ES-LF is an effective and economical PMIC solution that enables applications to operate with moderate to high power levels. Its integrated power control and monitoring circuitry allows for efficient and safe operation in a variety of applications.
