The FAN53840 is a Power Management IC (PMIC) for mobile power applications such as camera modules. The PMIC contains a high−power regulated channel for digital rails which can operate with an input as low as 1.0 V. Three channels are designed for ultra−low noise and high PSRR for sensitive analog/RF circuit loads. Each channel can be configured to operate as a pass−through load−switch, which reduces the input to output voltage drop and operating currents in critical low power applications. The FAN53840 provides the circuitry for setting and executing start-ups and shut-downs where the outputs can be individually controlled by setting I2C register bits. The PMIC monitors the voltage on each input and prevents the channel from operating if the voltage is below a safe operating level. In LDO mode, the device limits the current of each channel and protects againts short-circuits. Additionally, in LDO mode, if the device temperature rises too high, the device will shut down until the temperature cools to a safe operating level.

The FAN53880 is a low quiescent current PMIC for mobile power applications. The PMIC contains one buck, one boost, and four low noise LDOs.

The FAN54005 combines a highly integrated switch-mode charger, to minimize single-cell Lithium-ion (Li-ion) charging time from a USB power source, and a boost regulator to power a USB peripheral from the battery.The charging parameters and operating modes are programmable through an I2C Interface that operates up to 3.4 Mbps. The charger and boost regulator circuits switch at 3 MHz to minimize the size of external passive components.The FAN54005 provides battery charging in three phases: conditioning, constant current and constant voltage.To ensure USB compliance and minimize charging time, the input current limit can be changed through the I2C interface by the host processor. Charge termination is determined by a programmable minimum current level. A safety timer with reset control provides a safety backup for the I2C host. Charge status is reported to the host through the I2C port.The integrated circuit (IC) automatically restarts the charge cycle when the battery falls below an internal threshold. If the input source is removed, the IC enters a high-impedance mode, preventing leakage from the battery to the input. Charge current is reduced when the die temperature reaches 120°C, protecting the device and PCB from damage.The FAN54005 can operate as a boost regulator on command from the system. The boost regulator includes a soft-start that limits inrush current from the battery and uses the same external components used for charging the battery.
