MAX 77843EWV POWER IC

Description

The MAX77843EWV+T is a high-performance Power Management Integrated Circuit (PMIC) designed by Maxim Integrated, now part of Analog Devices. It serves as a companion PMIC for modern smartphones and tablet computers, integrating multiple power management functions into a single chip.

Key features of the MAX77843EWV+T include:

Dual Input Smart Power Path: A 3.0A switch-mode charger that supports reverse boost capability and can withstand adapter input protection up to 16V DC.

Fuel Gauge Technology: Incorporates proprietary ModelGauge™ (mg5) technology for accurate battery fuel gauging.

Low Dropout Regulators (LDOs): Includes two safe-output LDOs for stable voltage supply.

RGBW Driver: Features a four-channel driver for RGBW (Red, Green, Blue, White) LEDs, enabling advanced lighting effects.

Haptic Driver: Provides a driver for haptic feedback, enhancing user interaction through tactile responses.

Manual Reset and Customized MUIC: Offers manual reset functionality and a customized Micro-USB Interface Controller (MUIC) for flexible connectivity options.

Operating at a frequency of 4MHz, the switch-mode battery charger integrates low-loss switches, ensuring minimal heat generation and allowing for the use of smaller inductors and capacitors. This design contributes to efficient power management and compact device form factors.

The MAX77843EWV+T is available in a Ball Grid Array (BGA) package, making it suitable for space-constrained applications. Its comprehensive feature set makes it an ideal choice for managing power in advanced portable electronic devices.
