Controller IC Chip - MOFSET BQ24747RHDR BQ24747 24747 chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0343)
SMBus-Controlled Level 2 Multi-Chemistry Battery Charger with Input Current Detect Comparator and Charge Enable Pin
The bq24747 is a high-efficiency, synchronous battery charger with an integrated input-current comparator, offering low component count for space-constrained, multi-chemistry battery-charging applications. The input-current, charge-current, and charge-voltage DACs allow very high regulation accuracies that can be easily programmed by the system power-management microcontroller using the SMBus interface The bq24747 charges two, three, or four series Li+ cells, and is available in a 28-pin, 5x5 mm2 QFN package.
NMOS-NMOS Synchronous Buck Converter with 300-kHz Frequency and >95% Efficiency 30-ns Minimum Driver Dead-Time and 99.5% Maximum Effective Duty Cycle High-Accuracy Voltage and Current Regulation - ±0.5% Charge Voltage Accuracy - ±3% Charge Current Accuracy - ±3% Adapter Current Accuracy - ±2% Input Current Sense Amp Accuracy Integration - Input Current Comparator, with Adjustable Threshold and Hysteresis - Internal Soft-Start Safety - Dynamic Power Management (DPM) Up to 19.2-V Battery Voltage 7-V-24-V AC/DC-Adapter Operating Range Simplified SMBus Control Interface - Charge Voltage DAC (1.024 V-19.2 V) - Charge Current DAC (128 mA-8.064 A) - Adapter Current Limit DPM DAC (256 mA-11.008 A) Status and Monitoring Outputs - AC/DC Adapter Present with Adjustable Voltage Threshold - Input Current Comparator with Adjustable Threshold and Hysteresis - Current Sense Amplifier for Current Drawn From Input Source Charge Any Battery Chemistry: Li+, NiCd, NiMH, Lead Acid, Etc.
