描述 Description

DESCRIPTION
The LTC®4100 Smart Battery Charger is a single chip charging solution that dramatically simplifies construction of an SBS compliant system. The LTC4100 implements a Level 2 charger function whereby the charger can be programmed by the battery or by the host. A SafetySignal on the battery being charged is monitored for temperature, connectivity and battery type information. The SMBus interface remains alive when the AC power adapter is removed and responds to all SMBus activity directed to it, including SafetySignal status (via the ChargerStatus command). The charger also provides an interrupt to the host whenever a status change is detected (e.g., battery removal, AC adapter connection).FEATURES
■ Single Chip Smart Battery Charger Controller
■ 100% Compliant (Rev. 1.1) SMBus Support Allows
   for Operation with or without Host
■ SMBus Accelerator Improves SMBus Timing
■ Wide Output Voltage Range: 3.5V to 26V
■ Hardware Interrupt and SMBAlert Response
   Eliminate Interrupt Polling
■ High Efficiency Synchronous Buck Charger
■ 0.5V Dropout Voltage; Maximum Duty Cycle 98%
■ AC Adapter Current Limit Maximizes Charge Rate
■ ±0.8% Voltage Accuracy; ±4% Current Accuracy
■ Up to 4A Charging Current Capability
■ 10-Bit DAC for Charge Current Programming
■ 11-Bit DAC for Charger Voltage Programming
■ User-Selectable Overvoltage and Overcurrent Limits
■ High Noise Immunity SafetySignal Sensor
■ Available in a 24-Pin SSOP PackageAPPLICATIONS
■ Portable Instruments and Computers
■ Data Storage Systems and Battery Backup Servers
