BQ24735RGRR

Battery Chargers Overview

The BQ24735RGRR is a synchronous battery charger controller designed for 1 to 4-cell lithium-ion battery packs. It supports Turbo Boost mode, allowing simultaneous system power from the adapter and battery during high-load conditions. The device features an SMBus interface for programmable input current, charge voltage, and charge current limits with high accuracy. It operates within a 4.5V to 24V input range and utilizes a 20-pin 3.5x3.5mm QFN package.

Battery Chargers Feature Summary

• Supports Intel CPU Smart Boost Mode by enabling simultaneous power delivery from both AC adapter and battery sources.
• Features SMBus-controlled NMOS-NMOS synchronous buck converter architecture with internal charge pumps for N-channel MOSFET drive.
• Provides enhanced safety mechanisms including overvoltage, overcurrent, and short-circuit protection for batteries, sense resistors, and MOSFETs.

Battery Chargers Applications

• Portable computers and notebooks requiring intelligent power path management
• Industrial equipment utilizing multi-cell lithium-ion battery systems
• Medical devices needing precise battery charging profiles

Battery Chargers Procurement Notes
